Grey screen problem improved...

- Improved the grey screen problem by reworking the videoRecorder code.

- Added some more checking when unsticking stuck downloads. Found that
there are cases where FTM has OBtasks in state processing but no
nstasks associated.

KNOWN BUGS
--------------------
- Kill in the task manager then try to restart. Does not always start.
Sometimes dies and goes away. Sometimes get stuck on screen with all +
signs for friends.
- Downloading sometimes continues to show in the case where FTM has
obTasks in the processing state but no nsTasks associated with them.
