There is something wrong with the VLD decoding, I often get messages like 
this:

XvMCPutSlice: Error: 2
XvMCPutSlice: Error: 2

which switching back to xv decoding fixes. I also have experienced the CLE266 
decoder crashing hard, which I fixed in the old CLE266 decoding. This was 
occurring because incomplete slice arrays was sent to the decoder..
