[mythtv-users] MythTV and ivtv driver errors

My system: AMD Athlon XP 3000+, Geforce 6600GT, 1 GB ram, Hauppauge
WinTV PVR 150.
After some tweaking I got MythTv to work with the 0.3.3k ivtv drivers on
Gentoo linux. I can watch TV and record but I do see occasional MPEG
errors in the image and dmesg shows a steady stream of ivtv errors like:
ivtv: ENC IRQ OVERFLOW: #36842 Stealing a Buffer, 2 currently allocated
Mythfrontend gives errors like:
[mpeg2video @ 0xb7927810]invalid mb type in I Frame at 44 35
[mpeg2video @ 0xb7927810]ac-tex damaged at 43 35
[mpeg2video @ 0xb7927810]ac-tex damaged at 21 21
[mpeg2video @ 0xb7927810]Warning MVs not available
What is the cause of this error? When I use mplayer with ptune-ui I can
watch TV without any problem and I don't see the ivtv errors.
Should I tweak the livetv and recording profiles to increase or decrease
the data rate? I already changed the resolution of all profiles to PAL
The stream type for all profilss is MPEG2 PS. Does it make sense to
Any pointers would be very welcome. I have looked through all the info I
could find but nobody addressed this issue.
