[mythtv-users] skipping forward not working right anymore

[Marco Nelissen]

All of a sudden skip-forward during playback doesn't work right anymore.
It used to be instantaneous, but now whenever I skip there is a very
noticable delay and a distortion of the image that takes several
seconds to clear up.
Skipping backwards is still fine, and if I skip back and then forward
again, it is fine too. It's as if reading from disk has gotten extremely
slow, except it isn't: I still get over 50MB/second reading from disk.
Anyone ever seen symptoms like this?
