[mythtv] forward seek errors in previously recorded programs

Fri Nov 23 21:58:10 UTC 2007

Hi,

I am using trunk from ATrpms, r14921. When I fast forward through some
previously recorded programs, the progress bar jumps to the end of the
program however the forwarding does not work and the program continues
from where it was. If I attempt rewind at that stage, playback quits
and drops back to the menu.
This is the log from the frontend when fast forward is attempted:
