Will do, glad to hear  you run the same type of chipset, might be 
hitting you up on any problems I face on the 64bit setup.  Never ran VDR 
on 64bit yet, hope you don't mind.  I assume you are doing DVI out to 
your TV for the HDTV part of it.  Cuz I never see my projector truly say 
720p or whatnot when I tune to a HD Channel, just looks better.  Or is 
that something I have to tell xine to do?  Anyways, I started the 64 bit 
install during lunch will finish it up when I get home this evening.  
Thanks again for all your help, looking forward to making it work.  I 
did put my NVIDIA 5200 in to attempt the XVMC but due to you having 
issues with your Matrox, I will throw it in there too and see what 
happens between the two.
