[16:07] <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
[16:08] <hilo> tgm4883, 10.04
[16:09] <tgm4883> what version of MythTV?
[16:11] <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.
[16:12] <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?
[16:13] <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.

[16:20] <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

[16:23] <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
[16:27] <hilo> Okay thanks
[16:35] <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
[16:36] <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
[16:37] <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
[16:39] <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
[16:41] <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
[16:42] <rhpot1991> hilo: most likely a playback issue on your XBMC setup I'd say
[16:43] <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
[16:46] <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 :/
[16:47] <hilo> tgm4883, any reason why yours isn't in use?
[16:48] <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
[16:49] <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
[16:50] <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?
[16:51] <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
[16:52] <hilo> I am able to stream SD content from there without hickups most times. HD is less smooth
[16:53] <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
[16:54] <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
[16:57] <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?
[17:01] <rhpot1991> hilo: not really
[17:01] <rhpot1991> the closest you will get is a user job running on a completed recording
[17:02] <rhpot1991> and then watching just after the recording finishes
[17:02] <hilo> gotchya
[17:04] <hilo> Is it possible to set larger buffers on a frontend to allow for increased jitter over the internet?
[17:07] <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.
[17:14] <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
[17:15] <tgm4883> but your internet connection speed wouldn't be fast enough anyway
[17:17] <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?
[17:18] <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
[17:19] <tgm4883> hilo, what is your upload speed?
[17:19] <hilo> 8mbit
[17:20] <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
[17:21] <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
[17:22] <hilo> If I have commercial skipping disabled, can I remove commercials later on another mythbuntu box?
[17:24] <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.
[17:41] <hilo> Would virtualizing the backend cause performance issues?
[20:38] <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?
[20:55] <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
[20:58] <skunkworks> I found it - It is under information center.
[20:59] <skunkworks> I am trying to stream internet radio - or play mp3 streams
[21:25] <skunkworks> hmm - how do you play m3u streams through mythbrowser?
[21:26] <skunkworks> (wants to download them
[21:29] <skunkworks> or .asx
