[mythtv] Live playback / Timestretch

Hello,
I was just wondering if anyone was working on or planning to work on a
patch to use timestretch to keep live tv playback in sync. IE If playing
live tv and the current playback position is within 30 seconds of real
time, use timestretch to keep it there. If not, I would like to give it a
shot..

The thinking behind this is that in real use there always ends up being a
slight offset between record and playback speed. (Seems to mostly be
caused by poor audio hardware.) Some of my front end machines play faster
and run out of data causing a brief pause (very annoying), other ones are
a bit slower and fall behind (not as bad, but I personally don't like it
either). So, if the front end sees that the current playback position is
less than say 45 seconds behind current time, simply change the
timestretch value a very small amount plus or minus to keep it closer to
~20 seconds.

Any thoughts, or suggestions?
