Divx h264 beta 3 decoder and DVBViewer

Dear all,
as said in my feedback divx h264 beta 3 works good with DVBviewer but I think to have found a possible problem.
Every sometime I have some break up in the dvb-s signal of the channel Astra HD and Anixe hd.
But as usual they are really few.
Last day I had many breaks up and at every break up the memory usage raised up of 10 MB.
So I tested many render mode and the codec I have.
the results are that I saw raise up the memory usage with divx h264 codec with every render mode supported by DVBViewer (EVR included under windows xp (net framework 3)).
Hoping you will fix the problem.
If you need some further details just ask.
Seasons greeting.
Diego
