[mythtv-users] IVTV stops working, can't use test_ioctl?

[James S. White]

If you cannot use cat /dev/video > capture.mpg than the mythtv list is not
the place to be asking... The ivtv-devel mailint list would be more likely
to help you. That being said, what version of the ivtv driver are you using?
I had a similar problem with ivtv creating zero byte files, and updating to
this :

http://www.kernel.org/pub/linux/kernel/people/axboe/ivtv/ivtv-031118A-0.12.tar.bz2

fixed it.
