[mythtv-users] OT? pchdtv 5500 analog tuning problems

Chris:

Mine occasionally does this, too - switching from an HD to an SD channel,
I get static and color bands on a black/white picture - but it generally
lasts no more than 5-10 seconds, then goes away.  This only happens while
watching live TV.  Recordings from SD channels are clean, without the
static or the picture problems (I assume it's because Myth doesn't start
recording for several seconds after tuning the channel it needs)..

My pchdtv 5500 will sometimes fail to tune to a channel or give me strange
color bands in my picture.  It also only seems to happen when I go from
tuning an HD channel to tuning an SD channel.  When I go to watch a
recording, sometimes I'll get 1-2 good frames and then the rest of the
recording is all static video/audio.  Other times, the picture will be in
black and white, except there are horizontal repeating bars of red, green,
and blue that are each about 1/10th of the screen in width, which also bob
up and down a bit.  Other times, I'll get the bars and after a few seconds
they go away.

This didn't happen when I had my tuner in my other computer while I was
trying out mythtv.  At that time, I was using a 32 bit kernel (not using 64
bit), but I was using the same mythtv package, linux distribution, and
kernel version.  I have since tried using the trunk and 20-fixes - neither
of which solved the problem.

So is this a known problem with pchdtv 5500 cards in mythtv?  Or, is it a
known problem with the 64 bit driver?  Is there anything I can do to try and
fix it?
