Hi, 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 2.6.15.1 was much worse and fails more often and sooner, also on 2.6.15.1 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? So 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. Hardware info: I've got two avermedia cards plugged into a pci riser card in a mini-itx motherboard. The mini-itx is a bit odd as it only has one pci slot and the riser card splits this. 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. -- Thanks, M
