Well 4200-128MB is obviously easy as is DVI as CRT+DVI+TVout is the most common configuration. VIVO shouldn't be hard to find and will almost always come in CRT+DVI+VIVO form. So really it's the Mpeg4 which is confusing me a little as all other factors shouldeasily be for-filled.
I wasn't under the impression that any GF4TI cards came with any significant kind of MPEG/DVD decoding hw, the GF4MX have hw DVD but nothing more. The Rad8500 does have hw DVD while the Rad9000 and 9700 extend this to a degree for all MPEG video streams. However I am under the impression if you want a GF4TI you will either have to let your CPU do the processing (no prob on any AMD/Intel CPU 600mhz+) or else buy a hw PCI card.
Can you expand upon the Mpeg4 reference?
