Ive had this card working since it was supported in the cvs up until
about 4 weeks ago. Since then I am getting the following error when
loading the driver:
I have gone through a few of these cards, i have one that works fine
and have had no problems, others that started working then stopped,
others that never even started. Once it started happening i was never
able to resolve it (had two cards in one worked one didnt) changing
motherboard or powersupply made them all work fine though. All very
confusing and nothing indicating where the problem might be hardware
or software. I suspect it is a hardware thing. As such i have switched
to Hauppage Nova-t's I still have one 771 that works fine so leave it
alone, but if it fails i will replace it rather than try and solve the
problem.

It should be noted that loading mt352 afterwards makes no difference.
Loading bttv card=123 makes no difference. I can actually produce the
same output using just modprobe dvb-bt8xx. Ie bttv seems to be
autoloaded as does bt878 and mt352. You get eh following devices loaded:
/dev/dvb/adapter0/demux0

I am using the 2.6.16 kernel. V4l and dvb are all compiled as modules. I
am also using Udev. Im really rather stuck here. Id say it looks like a
bug to me in either the mt352 or dvb-bt8xx driver. The problem has
cropped up before but theres no resolutions posted on the maillinglist
or else where that i could find.
Any ideas?
Neil
