[mythtv-users] Fwd: Fedora Core 6 New recordings play back too fast

Can someone help me to understand Time Stretch? I see there are two
ways to set this:
- Press M, select Adjust Time Stretch, then pick one of the preset
options like 0.9, 0.5, etc.
- Press A, and use the left/right arrows to select the time stretch
It seems that if I use the A option, the selection is ignored unless
it matches the ones available in the M option. My problem is that the
audio on my playback is probably about 20% or so too fast. How can I
get this to work, if this is my best option?
