Been bashing my head against this one for a couple days now, was hoping someone on this list might be able to help.  Bought myself
an HD PVR, running on an Ubuntu 11.04 back-end, and custom-built the drivers per this page:
http://www.mythtv.org/wiki/Hauppauge_HD-PVR#HD-PVR_Driver_Compilation_Howto

Using 'cat /dev/video0 > test.ts' works great, the file plays fine with vlc.  However, when I tried to set it up to work within
myth, I get errors.  I ran my back-end using '-v all' in hopes of finding something more useful in the output, but I'm not seeing
anything obvious.  Here it is:

Looks like it tries a couple more times before completely giving up.  Given that catting /dev/video0 works fine, I'm inclined to
think this problem is on the myth end, and not the driver, cables, etc.  That said I've run the gamut of trying different usb ports,
cables, turning off legacy usb support in the bios, etc.  I'm always stuck with this same problem.

Hi Paul

The link you provided explains how to update to the latest linux-media. I did the same 3 days ago and got these messages too. 
Search for " DVB ioctl FE_GET_EVENT behaviour broken in 3.3" on the linux-media list, they are reversing/adapting the latest
changes.
