I'm having trouble getting good recordings from either of my PVR150 cards. I'm running KnoppMyth R5B7 (2.6.15-chw-2 kernel) and IVTV 0.4.4. I don't see any obvious errors (though I am a Linux noob) and the cards seem to work fine in that they do record and I can change channels and all that jazz.
I see blocky artifacts appear frequently--ever few seconds, sometimes nearly constant. Normally, I use the tuner input, though I've tried this with the composite input. I've tried changing the bitrate and using a lower one certainly makes it happen less, but doesn't eliminate the problem. Even a 1Mb bitrate--which results in an unwatchable picture--still shows this blocky behavior, though not as severely as with an 8Mb bitrate. I've taken a few screenshots, if it helps: http://www.danandsherree.com/miscfiles/1.png http://www.danandsherree.com/miscfiles/2.png Additionally, I see frames jumping out of order. A frame from perhaps 1 second in the future of the show will appear as I'm watching, if that makes sense. The last problem--of less importance, I suppose, is the sharpness of the picture. It's just not that good. Even with an 8Mb bitrate, the picture is significantly fuzzier than hooking the cable line up to the TV (which looks absolutely fantastic). >From the messages log: May 21 11:35:41 mythtv kernel: ivtv: ==================== START INIT IVTV ==================== May 21 11:35:41 mythtv kernel: ivtv: version 0.4.4 (tagged release) loading May 21 11:35:41 mythtv kernel: ivtv: Linux version: 2.6.15-chw-2 SMP preempt 586 gcc-3.3 May 21 11:35:41 mythtv kernel: ivtv: In case of problems please include the debug info between May 21 11:35:41 mythtv kernel: ivtv: the START INIT IVTV and END INIT IVTV lines, along with May 21 11:35:41 mythtv kernel: ivtv: any module options, when mailing the ivtv-users mailinglist.
