Well, at least I'm not alone. I was beginning to think I was as I not
found any posts about this issue. :)
I've seen the on a variety of different channels over the last month or
so. It seems to work ok if I record with outside of mythtv with cat
/dev/hdpvr > file.ts. It also seems work if I watch while it records
(that is as long as VDPAU doesn't give an error, but that's another
issue...). It would be nice if it gave some more information as to what
mythtv thinks detects the error as. I've tried turning on hdpvr driver
debugging and don't get much more there.
I've tried switching cables and put the HDPVR on it's side to help
ventalation. But I still get the error. I was running .21+fixes+hdpvr
and as far as I can recall I did not see this problem until I moved up
to trunk before .22 then .22RCs and later.
I have a Athlon X2 4200 on a MSI K8NGM2-FID (nforce MCP51) board. I'm
recording from DirecTV. What hardware are you running and what are you
