[mythtv-users] is my processor to blame? (lockups,
problems with FF and REW)

When I first went and looked at building a mythtv system I went
with what I knew[1] SuSE 9.1, got to the bit about installing
IvyTV drivers and after a bit more googling came across Jarod's
site. Because of the step by step instructions (and atrpms)
there I installed FC2, got it working (sort of) then because of
stability and sound issues[2] swapped HD's and installed FC3, got it working
then got fed up of the crashes/lockups and installed SuSE 9.1
again and it was *much* better, still crashed but not as often.
I traced my stability issues in the end to dodgy memory, SuSE *seemed*
to crash less but TBH that might be because I prefer SuSE.
Make your own mind up but personally I say go with whatever you are the most
comfortable with.
FWIW my SuSE 9.1 system (Pundit-R/Nova-T/PVR-350) has had *zero* crashes.
*HOWEVER* what I (and at least one other) have a problem with is if you play
a mpeg2 file with errors[3] through mythtv and the pvr-350 tv out you can
get
the screen to freeze (normally when FF/REW) with errors in the frontend log
such as
2005-02-23 15:27:26.722 Opening audio device '/dev/dsp'.
2005-02-23 15:27:26.722 Opening OSS audio device '/dev/dsp'.
2005-02-23 15:27:26.725 Using resampler. From: 0 to 1000 Using the PVR-350
decoder/TV-out

2005-02-23 15:27:27.113 Realtime priority would require SUID as root.
IVTV_IOC_GET_TIMING: Input/output error
ivtv rawframes descreased! did the decoder reset?

This doesn't lock the box but needs a reboot for the frontend/X to work
properly again.
