Hi All.

For some weeks now with current SVNs (can't say exactly since which one), MP crashes my PC when playing live TV while showing other visual elements (OSD, EPG with Live TV Window, ...).
Symptoms usually are loud stuttering sound (SPDIF), display is freezing or going out of sync. System has to be reset then, CTL-ALT-DEL will not work.
The crashes are frequent but occur statistically.
Probability is highest in EPG with Live TV Window, crash will occur in less than 60 sec when moving around in EPG. Stopping Live TV prevents the crashes (or at least makes them very much less frequent).
I do not think it is a hardware issue as system runs perfectly stable outside MP.
System stress test shows no errors.

Any ideas?
Anyone else who has that problem?

Regards, Markus
