Re: Show details - Re: NVIDIA Decoder Problems

Jon, put away any debugger, anything DDK related, and all that other stuff.
It's not needed and your causing more trouble for yourself trying to learn
wants going on. You getting to caught up in trying to find the most
technical explanation you can, but you are overlooking everything at
actually matters.

Drop the Cat 5.5 drivers, and go with 5.6 or 5.3. ATI did a horrible job
with 5.5, anything you test with those drivers should be disregarded now.

Grab the DirectX SDK and/or Graphedit. Read on MSDN about DirectShow
Merits.

Install whatever decoders you want to on a machine with an ATI video card in
it. Change the merit to the NVIDIA decoder to MERIT_PREFERRED = 0x800000.
Play MPEG-2 content in WMP, right click on the item in the playlist and
notice that NVIDIA's decoders are being used. Drag and drop the file into
GraphEdit, and notice the filter graph is built using NVIDIA's decoders. If
you see video, it's successfully working on an ATI card.

Now set NVIDIA's decoders to MERIT_DO_NOT_USE = 0x200000. Set Sonic's or
ATI/Cyberlinks as MERIT_NORMAL = 0x600000 or 0x800000. Notice which
decoders are now being used in WMP and GraphEdit. You can even un-register
the decoders using regsvr32.exe /u! There is not a need to uninstall
anything in order to test this equation.

All of these changes will also be reflected in DECCHECK.exe and DVDUPGRD
/Detect. It's all the exact same thing, just different interfaces to
configure it.

Of course, they want you to go purchase their hardware! Ford will tell you
to purchase parts through Ford Service, though you can goto AutoZone and buy
"brand x" and have it work fine. Ford is still going to say it's not
recommended, but that doesn't mean it's not going to work. They just want
your money. Basic marketing at play here, and your the exact reason
marketing exists. =)
