I attached very short sample DVD-Video files.
There is two titlesets, each titleset length is 9 seconds.

It was authored with DVDStyler 3.0.2 x86.
The format is NTSC 704x480, 16:9, 29.97fps.

I've sorry for the late reply.

I've been able to reproduce this issue with your sample (thanks!). It seems that the issue occurs when madVR tries to ask the DVD Navigator for some information, which madVR does once every half second. For some reason it seems that this gets stuck, which then somehow freezes the whole media player. I don't know how ffdshow raw processor is involved in this. I suppose I could probably find out, by spending dozens of hours of debugging, but to be brutally honest, ffdshow is a dead project, it's source code is horrific and nobody is there to fix bugs in it, anymore. So I tend to think that spending that much time debugging a dead filter might be wasted, when I could spend the same time doing something more constructive, no?
