FS,
Have you enabled the advanced controls in Zoom Player/DVD settings ? You should have 4 boxes to choose from. FFD Show is not the decoder, but a post-processor. If you want to use a good (free) decoder (which will be choosen in the two boxes on the right) you can install DeScaler 5, I don't think FFDshow will work correctly with the PowerDVD decoders... or maybe it's just the program itself that FFDshow doesn't work with...
Once you get to the advanced menu, in the box on the lower right, you need to add the special processing here, so select "add" and then choose FFDshow from the list. Then you will have to hit "register" selected codecs (or something to that effect). You will then need to setup FFDshow processing.
Sorry i'm not on my HTPC at the moment, otherwise i'd send you the link for the "simple" setup for FFDshow. As I remember, many people have problems with FFDshow and Zoomplayer and there is a registry mod and some other file that needs to be put in the ZP program directory to get it to run correctly... i'll post more tomorrow unless someone else comes up with it first.
cheers,

I believe this is what GadgetSmith was talking about. Great article about how to setup ffdshow.
