[mythtv] Video and Commercial Flagging Problems

[Warren Volz]

I posted this to the users list and got no response, so I am posting 
this on the dev list. Also, I'm having problems with commercial 
flagging automatically running after a show is recorded.

My email about video problems is below. I should add that I have 
verified that raw captures from my pvr-250 (ie: cat /dev/video0 > 
/tmp/junk.mpg) do not show artifacts.

I looked over the mythtv-users list and haven't really found an exact 
match to the problem I'm having. Video was working fine for 
recordings/live tv until a few days ago when I upgraded to the CVS HEAD 
version of mythtv. I would go back to the older version but transcoding 
wasn't working with 0.16.

My problem is that recordings and live-tv have noticeable mpeg 
artifacts when they are played/watched. I've gone through logs and I 
don't see any comments about DMA errors (it's on for both hard drives I 
have in my LVM volume), but there are lines like:

[mpeg2video @ 0x4089d010]slice mismatch
[mpeg2video @ 0x4089d010]00 motion_type at 24 14
[mpeg2video @ 0x4089d010]invalid mb type in B Frame at 28 29
[mpeg2video @ 0x4089d010]ac-tex damaged at 7 2


in mythfrontend's log. Thinking that my ivtv drivers were no longer 
compatible with this version of myth, I upgraded to the most current 
rc3* version (0.2.0-rc3f) but that hasn't helped. I've also checked 
recordings on my computer and the artifacts are being recorded in the 
mpeg not displayed on playback. Recordings before my upgrade play fine.

Any thoughts?

My system info is as follows:

MythTV - CVS HEAD
IvTv   - 0.2.0-rc3f
Kernel - 2.4.26 compiled with Slackware 10 default config options
