[mythtv-users] HDPVR cat video0 input output error. Everything seems in place

[Mark]

I haven't seen this error for a while and am not finding much in 
googling it for assistance.
I am wondering if this is a module problem in the kernel as it doesnt 
make much sense.

New Mythbox on F17
I know the HDPVR works as its fine on another F17 ( old ) box.

Problem: cat /dev/video0 > /tmp/vid.avi

Info:
ls -al /dev/video0
crw-rw----+ 1 root video 81, 0 Oct 30 15:19 /dev/video0

lsmod |grep hdpvr
hdpvr                  32337  0
v4l2_common            15099  1 hdpvr

hdpvr 2-1.6:1.0: firmware version 0x12 dated May  7 2009 23:27:43
[80987.350493] hdpvr 2-1.6:1.0: device now attached to video0
[80987.350519] usbcore: registered new interface driver hdpvr

So it all looks good.  I cant cat the video device as root or anyone in 
the video group.

Any ideas on what else I can check?
