I updated from the mythtv-0.21-203.fc10 x86_64 rpms to the bijou 205
rpms. I have 5.1 output mixed
down to 4 channels using this in .asoundrc that should sum center, sub
and left into left, center, sub
and right into right and rears into their respective channels.

pcm.51to40 {
  type route
  slave.pcm surround40
  slave.channels 4
  ttable.0.0 1
  ttable.4.0 1
  ttable.5.0 1
  ttable.1.1 1
  ttable.4.1 1
  ttable.5.1 1
  ttable.2.2 1
  ttable.3.3 1
}

Now with the  bijou 205 rpms, with at least CBS HD 5.1 shows the
channels are mixed up or shifted,
with the center channel coming out the left speaker and another
channel probably rears, coming out the right.
If I change the myth setup to do only stereo, it seems to be correct.

Are there any patches in this version that could cause this?

The VDPAU output seems to work fine on my 8400GS card, consistent with
previous reports as to which
deinterlacers work on the card and Myth seems to have some issues with
certain sound codecs, but that
happened before also. The shifted 5.1 audio is a new phenomenon.
