Aside from the completly frozen thing sounds this like an OSD related firmware 
crash. There might be nothing that can be done about it. Then again, you 
could just have hit one of two most resilent bugs in the dvd stuff.
I have be chasing a random memory corruption for the last few days. One i have 
found, but the other is still remaining. Both cause vdr to segault very early 
during dvd playback.
You can try if the following patch helps. It fixes a sizing problem with the 
IframeAssembler. But as i said, there is a second problem still pending.
