A strange problem with xmpeg

I'm successfully running xmpeg 4.5 with the current snapshot of wine. 
However, occasionally I get this very strange glitches:

1. When the splash screen desapears, so does all of my desktop. I have 
to make a Refresh Desktop to get it back. Judging by the log below, I am 
suspecting of something in the DirectDraw functions. Upon request I will 
gladily send a (45Kb) screen shot of this.

2. Whenever I click on a radio button for YV12 under Project 
Options/Post Processing, it crashes with the message

wine: main.c:572: DDRAW_width_bpp_to_pitch: Assertion `bpp != 0' failed.

I traced this down to the ddraw module and made the following very ugly 
hack around it by changing the macro PFGET_BPP to make sure it never 
returns zero:

Now it won't crash anymore, but when I click on that button, the whole 
dialog box gets misteriously sent to the back!

Anybody else having these problems? Any hints as to what could to be the
