Hello,

from time to time I use DVBcut to cut TV recordings made with a PVR, and
afterwards burn them on DVD.

This has always worked perfectly fine with my "good old" PC (a P4
running Windows XP Pro). However, after replacing that PC with a current
one (Core i3 with Windows 7x64), playback of the video doesn't work
correctly any more from within DVBcut. It appears as if there are some
problems with the interaction of the two threads (DVBcut and MPlayer)
and the operating system:

- The content of the video window is not constantly refreshed. Only if
  redrawing the window area is necessary for some other reason (i.e.
  moving another programs window overlapping to DVBcut), the related
  part of the video window is correctly redrawn.
  I assume that Windows 7 doesn't get the information that the content
  of the DVBcut window needs to be refreshed due to new content of the
  Mplayer window within it.
  If Aero is activated, screen refresh seems to work significantly
  better. Obviously, Aero forces some kind of "continuous screen
  refresh" (wasting ressources...).
- After playback has been started, it cannot be stopped anymore. The
  only way to stop it is by closing DVBcut. As above, I assume that the
  mouse click on the stop button is not properly transferred to the
  MPlayer thread that runs "inside" the DBVcut window.
  (Activating Aero doesn't change anything here.)

If I start the playback with Mplayer by command line, the video is shown
perfectly, so it's pretty obvious it's not a missing codec or the like.
(All other players I tested also work fine and smooth.) All without Aero
(which I don't like, BTW).

Does anybody (successfully) use DVBcut with Windows 7 (x64), including
MPlayer playback within DVBcut? If so, I would like to share some
details about system setup etc. - if not, would someone dare to have a
look at this problem? If more tests need to be done, that's no problem -
I'll try to help as much as I can.

Many thanks in advance,
Tilmann Reh
