| Araya213 | Hello, I've had an ongoing problem that I've just never gotten around do fixing. I'm on the latest mythbuntu with fixes and have 2 a master and slave backend. Each one is running a pvr-150 and an HVR-1600. I'm having signal quality issues with all tuners. Some channels just come in very poorly while others look fine. Is there a way to fine-tune the frequency my tuners are using? | 03:21 |
|---|---|---|
| Araya213 | It might also help to note that if I plug the cable directly into the TV everything looks fine. | 03:23 |

| bazhang | nice | 03:24 |
| Araya213 | Oh yes, one more thing. A while back I tried using a powered cable amplifier, it did not help at all. | 03:26 |
| Shadow__X | Araya213: does analog and digital both look bad | 03:46 |
| Araya213 | No, only analog, digital is pretty as pie | 03:47 |
| Araya213 | One thing though, The tuner cards are right next to each other on the motherboard, could that cause interference? | 03:49 |
| Shadow__X | hmm at that point i would point towards it being an analog issue | 03:49 |
| Shadow__X | when i tried to record analog the quality was bad so i just ditched it | 03:49 |
| Araya213 | Not an option in this case | 03:50 |
| Araya213 | Do you know if it's possible to manually set the frequencies for certain channels? | 03:50 |
| Shadow__X | possible? just not sure where to do that | 03:50 |
| Araya213 | I've looked all over the back and frontend settings, unless it's well hidden it's not there. | 03:51 |
| Shadow__X | it would be in the backend settings | 03:51 |
| Shadow__X | but again i am not sure i have never done that | 03:52 |
| Araya213 | You can change the frequency table, and I've tried all of the US ones, but nothing for individual channels | 03:52 |
| Araya213 | Hello, I've had an ongoing problem that I've just never gotten around do fixing. I'm on the latest mythbuntu with fixes and have 2 a master and slave backend. Each one is running a pvr-150 and an HVR-1600. I'm having signal quality issues with all analog tuners. Some channels just come in very poorly while others look fine. If I plug the cable directly to the TV everything looks | 04:42 |
| Araya213 | great. A while back I tried using a powered splitter and it didn't help at all Is there a way to fine-tune the frequency my tuners are using? | 04:42 |
| Shadow__X | Araya213: are you sure its using analog on the tv when it looks great? | 04:43 |
| Araya213 | Yes | 04:44 |
| Shadow__X | do you have a picture of how bad it looks? | 04:44 |
| Shadow__X | the reason why i ask is i am thinking it looks great on the tv because its an old tube and you are watching the recording on a lcd monitor and because of this it looks bad | 04:45 |
| Shadow__X | but thats just me guessing | 04:45 |
| Araya213 | I have several TVs, one of them is an old DLP, but the quality issues are very obviously signal based, wavy lines and such, I'm trying to get a pic now | 04:47 |
| Shadow__X | have you looked around the mail logs? | 04:47 |
| Araya213 | I don't know what that is. Care to get me up to speed? I've done ton of googling though. | 04:48 |
| Shadow__X | this is an archive of the mailing list | 04:48 |

| Araya213 | I'll check it out, how do I screenshot in mythbuntu? | 04:49 |
| Shadow__X | print screen? | 04:49 |
| Shadow__X | i am not really sure | 04:51 |
| Araya213 | I'll try it, what's a good image editor to use for ubuntu? I don't really know much about the desktop aspect of ubuntu, don't really use it for that. | 04:51 |

| Zinn | [wiki.archlinux.org] Xfce - ArchWiki | 04:52 |
| Shadow__X | mythbuntu uses xfce as the window manager | 04:52 |
| Araya213 | it's hard to get a decent screenshot of live video | 05:00 |
| Araya213 | working on it htough | 05:00 |
| Shadow__X | you could pause it | 05:02 |
| Araya213 | LOL Duh | 05:02 |
| Araya213 | Here's a screenshot of what my problem looks like. It only does this on certain tuners on certain channels, but all of the tuners do have this issue. http://imgur.com/Xkl9L | 05:05 |
| Zinn | [imgur.com] imgur: the simple image sharer | 05:05 |
| Araya213 | indeed | 05:06 |
| Shadow__X | oh wow hmm | 05:06 |
| Araya213 | Pretty ugly huh? | 05:06 |
| Shadow__X | yeah i think that has something to do with attenuation | 05:06 |
| Araya213 | but if I switch over to another tuner, it looks fine, but then that tuner has other channels that look bad | 05:06 |
| Shadow__X | hmm you said they are right next to eact other right?m | 05:07 |
| Shadow__X | try removing one tuner and seeing if all the chanels are ok | 05:07 |
| Araya213 | I have tried that, no dice | 05:07 |
| Araya213 | Also, this happens on both backends | 05:07 |
| Shadow__X | have you tried putting a regular splitter infront of the tuner? | 05:08 |
| Araya213 | Yes, I'm using a regular splitter, but the problem happens wether I'm using a splitter or not | 05:09 |
| Araya213 | I really think it's some kind of nonstandard frequency usage on the part of my cable provider. | 05:10 |
| Shadow__X | perhaps there is too much signal strength? i am really not sure, i can give you suggestions but i am unsure if it will fix your problem | 05:10 |
| Shadow__X | i know analog is a lot trickier than digital | 05:10 |
| Araya213 | I'll take all the hlep I can get | 05:10 |
| Araya213 | help too | 05:10 |
| Shadow__X | why do you think its a nonstandard frequency? your tv's are able to pick it up | 05:10 |
| Araya213 | yeah, you're right. | 05:11 |
| Araya213 | that kind of rules that out | 05:11 |
| Araya213 | Unless my TV is not as sensitive to it as my tuners | 05:12 |
| Araya213 | don't know if that's even a possibility though | 05:12 |
| Shadow__X | not sure. I know when i was using analog i was having a bunch of problems | 05:13 |
| Shadow__X | oh also did run the cable in your house? | 05:14 |
| Araya213 | I havne't messed with the cable at all, it was here when I moved in | 05:15 |
| Shadow__X | i am really not sure but you can go to the mythtv-users channel and ask them they would know better than i | 05:15 |
| Araya213 | right on, i'm headed that way | 05:15 |
| kb1gtt1 | Well, I got irw working, it now receives signals. Is there anyone that can help with irsend around here? Syslog notes uirt2_raw: UIRT tried to send 237 bits, max is 128 I'm drawing a blank about how to fix it | 05:59 |
| rileyp | Is suspend with diskless possible? I'm using lucid mythbuntu and it does resume to the gui and firefox works if I left it running prior and dmesg works as well but for example nano or mythfrontend or any other application for that matter will not I get an error in dmesg regarding squashfs and ndb block device being unable to connect to | 14:01 |
| rileyp | where does one define whther to suspend to disk or ram | 14:25 |
| kb1gtt | I just added a section to this wiki. https://help.ubuntu.com/community/Lirc_USB-UIRT#Specific to Mythbuntu 11.04 I got the usbuirt working, but the config scripts from mybuntu control centre will break it and didn't work out of the box. | 15:28 |
