It seems to work more often from a cold boot... I've also noticed the 
following.... I have been having intermittent problems with my ps/2 
mouse, regardless of what kernel I am running, but have NO mouse 
problems in windows.  When the ps/2 mouse isnt working, I just use my 
usb mouse instead.  Anyhow, I have noticed that when the ps/2 mouse 
doesn't work, DVB doesn't work either.  The module loads up and 
everything seems correct, but I just cant get a lock.... In these cases, 
I will always get status code 0x00.

I tested 2.6.13-rc2-mm1 and everything works fine (of course i have my 
intermittent problems, but this is MY problem -- not the driver).  I 
didn't try 2.6.13-rc2-git2 yet ... Will try tonight or over the weekend.

HD works just fine for me. Are you sure the problem that you have might 
not be because of the video board that you're using?  (just a guess)  
However, I must say:  I have been using a combination of azap and 
mplayer to do my testing -- mythtv still isnt working.  Using mplayer, 
no matter what channel I am viewing, the video stream only lasts for a 
finite amount of time.  I am getting a bunch of crc errors.  I would 
like to share this output with you... I will try to capture some of this 
later on.

The HD streams seem to be more volitile than the SD streams.  I haven't 
had a HD stream last for much longer than a minute or so, but I've had 
SD stream last for as long as 20 minutes.

I don't know anything about this.... (ber)  Maybe someone reading the 
list will respond with some info....
