I have similar issues (and some extra symptoms, hope I'm not abusing this 
list) with my MSI tv(at)nywhere A/D hybrid.  It has got similar chips to 
these cards you got.  The most noticable (physically that is, I've got very 
little clue what each one does)


With recent drivers I've got no luck trying to get card funtioning, usually 
resulting in some issues with firmware loading.

I'm running now on ubuntu 8.04 but booting with 2.6.20-13 kernel and stock 
ubuntu drivers.  This setup works most of the time but requires reloading 
drivers after first (dvb-t) use of card, and often after a few days and some 
recordings signal level drops to 0%.

Any attempt to try using analog, which is not working now but used to, results 
in Frontend initialisation failure for dvb, only rectified by powering down 

I've got very limited technological skills in this area but am quite willing 
to do some testing if I can help.
