Playback Controls Wont Work In Mydvd

[ThePad]

I was putting the finishing touches to a MyDVD project when I found the playback controls in the editing window wouldn't work anymoer - that is:

 

Pause, frame advance forward, play, go to clip start, go to clip end, go to start of project and go to end of project, etc.

 

None of the icons work - they are all greyed out. Cut, copy and paste etc will not work when right clicking a clip.

 

The shuttle ring also does not work. I can drag the seek bar across the timeline but the video will not play as the slider is dragged.

 

Curiously, if I double click a clip, the clip editing window will open, and I can play back the video in the editing window.

 

Other projects already on my PC seem to open and work without any problems.

 

So I figure it is one of two things.

 

1. The dmsd file has become corrupt (hope to hell that is not the case, but fear it is).

2. I have accidentally hit some control or other and switched off some of the functionality of the editing window. (praying that is what has happened).

 

Any comments on how I could fix this would be greatly appreciated.

 

TIA
