[mythtv-users] KWorld ATSC-115 problems -- can't change channel, no sound

[David Lonie]

Another piece of the puzzle that may help ya'll help me.

If I select watch TV, it starts off on the KWorld tuner, where the
audio is high pitched and studdered and the picture is very poor, the
backend log shows:

Please go into the TV Settings, Recording Profiles and setup the four
'Software Encoders' p
rofiles.  Assuming RTjpeg for now.
2009-01-02 12:35:10.615 NVR(/dev/v4l/video1) Error: Unknown audio codec

I switch to the PVR-150, where everything is fine, then back to the
kworld where I get the same message as above in the log, and the
backend dies without an error message at this point.

I've looked at the TV Settings, and I have the RTjpeg and MPEG-4
option available as the codecs. IIRC RTjpeg should be correct for
saa7134 cards, so I don't see what the problem is.

Any ideas?
