Ah, thanks, that makes much more sense now, and some things seem to
work better this way.
driver: ivtv-0.7.0 (tagged release)
card: Hauppauge WinTV PVR-150, bus info 0000:02:04.0, ivtv card #0
hardware: cx25840 tuner wm8775 tveeprom
/dev/video24: PCM encoding (links: /dev/video)
/dev/vbi0: VBI encoding (links: /dev/vbi)
/dev/video0: MPG encoding
/dev/video32: YUV encoding
But it's still confused about the channels, what I have now under
MythTV Status (mythweb):
Encoder 1 is local on tivi and is not recording.
Encoder 2 is local on tivi and is not recording.
The next 10 shows that are scheduled for recording:
Sun 2/18 3:00 PM - Encoder 2 - Bravo - Law & Order: Criminal Intent
Sun 2/18 3:00 PM - Encoder 1 - G4-video game television - Arrested Development
So, right there you can see a problem... one of my two encoders
(encoder 1, I think) is just an OTA pcHD3000, so it's going to have a
hard time getting cable shows :(
