[linux-dvb] Avermedia 771 random failures

I've had two problems the most anoying is that from time to time the
card just stops working.
Origonally I thought it was due to a borderline power problem (PSU now
much improved) however I've noticed the 188.8.131.52 was much worse and
fails more often and sooner, also on 184.108.40.206 sometimes the card
"recovers" sometimes it doesn't. The symptoms are unable to tune the
card. Under mythtv this appears as a failed record and I've also seen
loss of audio though this is much rarer.
The kernel that currently works well and I see less failed recordings is
2.6.12-rc3 however it does still happen.
I was seeing a lot of mt352_read_register errors when booting this
kernel, I'd reboot untill it worked, sometimes leaving it off for a few
minutes helps, this read error is less common on the newer kernel but
sadly the card fails sooner.
I've seen a few posts on the register read error, but none on failure to
tune. It seems a nasty intermittent problem does anyone else suffer from
it? Is it a driver problem, were there any specs released? Any
suggestions for tracing it?
Are people using two cards with success on a machine that is switched on
all the time?
2.6.12 - can't reliably see card at boot - read register problems.
2.6.15 - card stops responding to tuning requests but booting seems better.
I've got two avermedia cards plugged into a pci riser card in a mini-itx
The mini-itx is a bit odd as it only has one pci slot and the riser card
Origonally it had a 120W PSU, the mother board is very low power, I've
now got a 300W PSU so I'm failrly sure the PSU is not the problem.
Also using the infra red remote on one of the cards.
