[mythtv-users] Problem with IVTV - video is wrong length

Sun Sep 2 06:58:11 UTC 2007

I have two video capture cards, a Hauppauge PVR-500 and the PCHDTV-2000. 
  I've never had any problems with them before.  When I did my latest 
MythTV upgrade, I went to CentOS 5 instead of using Fedora like I have 
in the past, because atrpms.net supports CentOS releases for longer.

The problem I'm having now is that my IVTV driver is recording shows a 
little funny.  For example, a 1-hour recording will show up as 1:08:50 
(+/- a few seconds) when I press the info button while watching it. 
However, it actually is only about 55 minutes long.  Commercial skipping 
works fine.  When I play from bookmark, it goes to the wrong place, but 
doing the skip rewind (mine is set for 5 sec) puts it back in the 
correct location.  If I try to skip forward past the end of the show, it 
just freezes up.  Playback keys stop working, but I can still jump back 
to the main menu.

My PCHDTV records things just fine, and playback is fine.  I've tried 
playback on multiple front ends, and get the same symptoms, so I'm 
pretty sure the recordings are just screwy.  I'm not sure what options 
to share.  I'll give all of the information I can think of.

My default recording profile is 720x480, MPEG-2 PS (I've tried others 
with no difference), 4:3, 4500 bitrate, 6000 max bitrate, 48000 sampling 
rate, layer 2, 384 kbps, 100% volume.

I have this in my modprobe.conf:

options ivtv enc_mpg_buffers=16 enc_vbi_buffers=8

Here is the dmesg output:

Any ideas?  I've tried lots of things, with no success.
