Its time to upgrade the mythtv backend. Since I have to burn in the new
hardware I thought it was a good time to test this sound issue on a brand
new FC14 mythtv, mysql installion. The last test of a 1080i recording
(HDHomerun) with 6 channel sound resulted in the slow speed sound in
the recording.
kernel 2.6.35.12-90.fc14.x86_64
mythtv version from atrpms mythtv-0.24-271.fc14.x86_64
I set up four Transcoder profiles.
Autodetect from 1080i 720P 480i and 480P
1080i 720P 480i 480P
Lossless enc no no no no
Resize video no no no no
bitrate 3000 3000 2000 2000
Max qual 2 2 2 2
Min qual 15 15 15 15
Max diff 3 3 3 3
scale no no no no
Enable h qual yes yes yes yes
En 4MV yes yes yes yes
Ena DCT no no no no
Enable Inter emo no no no no
Num threads 2 2 2 2
codec uncomp uncomp uncomp uncomp
sampling rate 48000 48000 48000 48000
volume 90% 90% 90% 90%
Hopefully this answers the question about the "parameters"
passed for transcoding. If not your going to have to provide a
hint as to where I can find the parameters mythtv uses for transcoding.

more than likely the video is actually 1080 so mythtranscode will treat
