If you use the the LAV CUVID decoder and use the new decoder property option in the latest version of ProgDVB to make any changes, the decoder will stop working the next time you start Prog. The only way to fix this is to remove any setting from your registry!
This is for the 32bit verstion 0.13 - 2011/09/13 and may be the same with other versions.

Please send me over mail THIS version of lav.

зы: Can I test on ATI?

Already sent. Not sure if it works with ATI graphics.
The problem is obviously with the decoder and not ProgDVB and my post is just a word of warning to others as to what may happen if you are using this decoder.

I like this forum, amazing and very informative,
