[mythtv-users] Odd pauses when starting recorded shows...

[mythtv at varga.co.uk]

Now that my Myth box seems to be fairly stable, I'm slowly starting to
migrate recording shows off the Tivo and onto the Myth box. As I'm
actually using Myth a lot more, I've noticed a few problems...

1) When I select a recorded show to play from the menu, on about 20% of
them, the screen goes black and there is no sound, it sits there like this
for anything from 10-45 seconds and then the show starts and plays as
normal...
I've run the database check and it's all fine and playing the files over a
samba share is OK too. Playing videos in MythVideo has no problems...

2) Scrolling up and down the recorded shows menu, occasionally pauses for
a few seconds, with what sounds like harddrive thrashing about, before
continuing as normal, this is a minor problem, but it's SOOOOOO
annoying...

3) When using the 30 second skip, it skips and then kind of does slow
motion for about 1 sec or 2 and then plays properly. Is this normal? or is
there a problem? It's annoying after using the 30sec skip on the Tivo for
years...

Any ideas? It's really impacting the WAF...

Cheers,
Lee
