Carl,
Can you provide any suggestions on how to get VBI data under ivtv
0.7.0 with a PVR-500? I'm running 0.7.0 but haven't been able to grab
captioning data. I've been up and down the mythtv-dev and ivtv-dev
lists on gossamer and there's little information there.
When I try to activate the cc passthrough I get
$ ivtvctl -w cc -d /dev/video0
ioctl IVTV_IOC_S_VBI_PASSTHROUGH failed: Invalid argument
Anything you can provide would be helpful,
Mark
