This would explain why it happens more easily after a channel switch. I
still don't understand why a smaller menu will be shown after the problem
occures, but I guess we need the sources for this.

I can confirm this. It hasn't crashed here as well after some 10 minutes of
playing with osd.

The menu gets slower tough. I can suggest changing the value of MenuColumns
(dvbapi.h) from 40 to 30. This compensates for the delay introduced in the
OSDCOMMAND call (but if you have very long channel names, leave it at 40).

Good Job!

Plamen.

PS for Ralph: Hope this new info is of help for fixing OSD in the firmware.
