| hilo | hello, I have an HD-PVR which I purchased specifically for Mythbuntu. I haven't been able to get it working even a little bit. Can anyone offer advice? | 16:07 |
|---|---|---|
| tgm4883 | hilo, what version of ubuntu are you on? it should work OOTB | 16:07 |
| hilo | tgm4883, 10.04 | 16:08 |
| tgm4883 | what version of MythTV? | 16:09 |
| hilo | I am not sure. I have reformatted for a fresh start after lots of failure. | 16:11 |
| tgm4883 | why 10.04 and not 12.04? | 16:11 |
| hilo | When I installed, 12.04 was not available yet. In addition I use 10.04 on all my desktops and servers. | 16:11 |
| hilo | I have no reason not to use 12.04, especially if the HD-PVR has a better chance of working. | 16:12 |
| tgm4883 | hilo, no, it should work in 10.04 | 16:12 |
| tgm4883 | do you have the hdpvr 1212? | 16:12 |
| tgm4883 | and not the 1482 hd-pvr2 gaming edition? | 16:13 |
| hilo | correct, NOT the gaming edition. I have to check the exact model though. | 16:13 |

| hilo | I read something on the MythTV site about firmware versions, but I don't see anywhere to download or install firmwares from Hauppauge's site. Am I missing something? | 16:20 |
| hilo | I never updated the firmware and my HD-PVR is about 2 years old | 16:20 |

| Zinn | [www.hauppauge.com] Support for HD PVR | 16:23 |
| rhpot1991 | firmware there | 16:23 |
| rhpot1991 | you need to update it via windows as far as I'm aware | 16:23 |
| rhpot1991 | last I tried it didn't work from vbox either | 16:23 |
| hilo | Okay thanks | 16:27 |
| hilo | Can you help clarify system requirements? I want to run the a backend with the HD-PVR connected recording live TV from a cable STB. The backend will not serve any playback/frontend functions. Do I need a graphics card at all to get smooth recordings? | 16:35 |
| tgm4883 | no | 16:35 |
| tgm4883 | well, you'll need at least some form of graphics for setup | 16:35 |
| tgm4883 | but not for playback | 16:35 |
| tgm4883 | you could probably stick an 8MB card in there from 1990 | 16:35 |
| hilo | Using an integrated card won't degrade my recordings though right? | 16:36 |
| tgm4883 | correct | 16:36 |
| tgm4883 | video cards have nothing to do with recording quality | 16:36 |
| hilo | Playback will be on a raspberry pi running XBMC with the Myth frontend plugin | 16:36 |
| tgm4883 | the hdpvr compresses the stream to h.264, so all the backend is doing is writing a file to disk | 16:37 |
| hilo | So even CPU requirements should be low for recording?> | 16:37 |
| tgm4883 | yea | 16:37 |
| hilo | When a frontend tunes into 'live' TV, does the backend save a recording file, or is a video streamed directly across the network? | 16:39 |
| tgm4883 | backend saves a file, then reads from that file to give to the frontend | 16:39 |
| hilo | So for a backend, I/O performance is likely the bottleneck if recordings are jittery? | 16:41 |
| rhpot1991 | CPU is used for commflagging and things like that | 16:41 |
| tgm4883 | yea | 16:41 |
| rhpot1991 | which I'm not sure XBMC utilizes | 16:41 |
| rhpot1991 | so you can disable those jobs if so | 16:41 |
| rhpot1991 | hilo: most likely a playback issue on your XBMC setup I'd say | 16:42 |
| hilo | rhpot1991, I haven't actually gotten my backend to even record yet :) I'll be starting with a fresh installation tonight and I'll report back | 16:43 |
| hilo | I had actually given up and assumed my HDPVR was faulty, but I have my fingers crossed it was just crappy firmware. It's been sitting on a shelf collecting dust for over a year now | 16:46 |
| tgm4883 | mine is sitting in a box :/ | 16:46 |
| hilo | tgm4883, any reason why yours isn't in use? | 16:47 |
| rhpot1991 | mine is still hooked up, but hasn't recorded since I got my hdhr prime | 16:48 |
| tgm4883 | hilo, It works great, I've just upgraded to an HDHomerun Prime | 16:48 |
| hilo | tgm4883, cool, I considered that as an alternative. | 16:48 |
| rhpot1991 | my hdpvr stopped working for a bit, bad ps | 16:48 |
| rhpot1991 | hilo: prime is great if you are in an area where the cable co doesn't flag anything | 16:49 |
| hilo | rhpot1991, that was directed at you | 16:49 |
| rhpot1991 | errr everything | 16:49 |
| rhpot1991 | so pretty much not TWC | 16:49 |
| hilo | I live in a TWC area, but the HD-PVR is at my parents who have Optimum. | 16:50 |
| rhpot1991 | planning on streaming across the intertubes? | 16:50 |
| hilo | I was going to try. Their Optimum Online upstream is average 8mbit | 16:51 |
| rhpot1991 | doubt it will work well | 16:51 |
| hilo | If that doesn't work, I can live with recording then rsync | 16:51 |
| hilo | I am able to stream SD content from there without hickups most times. HD is less smooth | 16:52 |
| hilo | I have my fingers crossed the upload pipe will continue to grow though as it has more than doubled in the last 3 years | 16:53 |
| hilo | But like I said, if streaming can't fit, I am fine with recording, then having it rsync to my local storage | 16:54 |
| hilo | I don't watch much sports, so true live tv isn' | 16:54 |
| hilo | isn't really a deal breaker | 16:54 |
| hilo | Is it possible to transcode live tv to allow streaming to work over that connection? Or is the only option lowering the bitrate of the HD-PVR? | 16:57 |
| rhpot1991 | hilo: not really | 17:01 |
| rhpot1991 | the closest you will get is a user job running on a completed recording | 17:01 |
| rhpot1991 | and then watching just after the recording finishes | 17:02 |
| hilo | gotchya | 17:02 |
| hilo | Is it possible to set larger buffers on a frontend to allow for increased jitter over the internet? | 17:04 |
| hilo | For example, instead of a 5-20 second buffer (which seems to be about what I got with Boxee and XBMC file playback), could I buffer at the frontend such that live tv is 5 minutes delayed to allow a large buffer (5 minutes of buffer)? This way when the network chokes for a minute or two, the video playback is unaffected. I have read that this approach is wrong, but when using shared networks like the internet, I don't understa | 17:07 |
| hilo | nd why. | 17:07 |
| tgm4883 | hilo, mythfrontend doesn't allow setting a buffer. If you are using XBMC for a frontend, you would set the buffer there | 17:14 |
| tgm4883 | the backend would have nothing to do with a buffer | 17:14 |
| tgm4883 | but your internet connection speed wouldn't be fast enough anyway | 17:15 |
| hilo | tgm4883, I don't understand why it isn't fast enough. If I record a 30 minute episode, I can generally download that file in less than 30 minutes. Doesn't that mean I should be able to stream it live if the buffer is big enough to account for the sporadic chokes? | 17:17 |
| tgm4883 | hilo, but you aren't downloading it. You are uploading it | 17:18 |
| tgm4883 | wait, maybe I'm misunderstanding what you are saying | 17:18 |
| hilo | tgm4883, I mean when I upload it to myself at another location | 17:18 |
| tgm4883 | hilo, what is your upload speed? | 17:19 |
| hilo | 8mbit | 17:19 |
| tgm4883 | nice | 17:20 |
| tgm4883 | I think mine is pretty crappy, but IDK | 17:20 |
| tgm4883 | in theory it could work | 17:20 |
| hilo | :) it was a recent upgrade | 17:20 |
| hilo | in theory :) which I spend way too much time theorizing | 17:20 |
| tgm4883 | there will be a slight overhead because of the myth protocol | 17:21 |
| tgm4883 | and if you don't do commercial skipping, that will help as well | 17:21 |
| hilo | okay, good to know | 17:21 |
| hilo | If I have commercial skipping disabled, can I remove commercials later on another mythbuntu box? | 17:22 |
| tgm4883 | hilo, well it's more that if you tried to skip commercials while streaming remotely over the internet, then its possible it wouldn't have cached the end of the commercial yet | 17:24 |
| tgm4883 | which would cause issues | 17:24 |
| hilo | lol also I just realized where a 5 min buffer would not work well: Channel changes would be hella delayed | 17:24 |
| hilo | makes sense. | 17:24 |
| hilo | Would virtualizing the backend cause performance issues? | 17:41 |
| skunkworks | stupid question - I installed mythbrowser through the control panel - how the heck do you use it? I don't see a button anywhere. what am I missing? | 20:38 |
| tgm4883 | skunkworks, I don't use it myself, but I think it should be listed in the frontend somewhere | 20:55 |
| tgm4883 | either at the main level or 1 deep | 20:55 |
| tgm4883 | IIRC, there is an information one or something. Similar to where mythweather would be | 20:55 |
| skunkworks | I found it - It is under information center. | 20:58 |
| skunkworks | I am trying to stream internet radio - or play mp3 streams | 20:59 |
| skunkworks | hmm - how do you play m3u streams through mythbrowser? | 21:25 |
| skunkworks | (wants to download them | 21:26 |
| skunkworks | or .asx | 21:29 |
