1. Start MP
2. Go to MyTV
3. TV is playing

Problem:
When watching TV I get a heavy dropout around once per minute. The dropout is around 1 second long. Every time I get a dropout, in Mediaportal.log apears the message VMR9Helper: repaint->playing 1.

I have tried out to enable or disable DirectX exclusive mode. No change.
I also completely reinstalled Windows and Mediaportal. No change.
And no, it is not the signal quality (always at 100%). MyTheatre works without any problems.
The dropouts appear on encrypted and also on non-encrypted cannels.

This dropouts appear also in recorded shows. I can see them when demuxing the recorded file with ProjectX. Also when simply watching it. Dropouts in recordings appear also when recording in background (without watching while recording).

MyVideo is playing without any problems. So the problem seems TV related.

I noticed this problem since 0.2 RC2. It appears also in actual SVN builds.

The Problem is not longer existant.
It was a problem with channel scan. Mediaportal did not select the correct tuning parameters. Additional I had to select PID-filtering. Now in works.

In release 0.2.2 the channel scan works without this problem.
