Hi Lisa,
I was originally using the nVidia decoders with hardware accell' but I found to get smooth motion I had to use Reclock which didn't work very well with VRM9 in MCE. I also found the colours a bit subdued. Otherwise it gave great picture resolution (going DVI into my Pioneer 50MXE1 plasma 1280x768@50Hz).
I am now using the WinDVD 6 codec and I find motion is near perfect without Reclock and the colour reproduction is much more to my taste. I am using the Windows MCE frontend which gives me great results but I am also experimenting with
Media Portal using ffdshow to resize and the WinDVD 6 codec.
I would definitely recommend the card to anyone building a new system but wouldn't like to say whether it would be a worth while upgrade for you not having chance to compare the two cards. Unless your using HD video then I guess the hardware would make a big difference.
I built my system just after Christmas but haven't really had a great deal of time to tweak it. If only I could find a way to still get paid without actually having to work
Obviously I like the idea of "Pure Video" but I find I get a more pleasing picture with WinDVD 6, other peoples setups may give different results.
Maybe a future version of nVidia DVD will work better for me.
I got my card just after Christmas from
Armari but it was part of a deal I have with them, they are not really a "box shifter" type of company more of a bespoke PC manufacturer.
Sorry I can't be more help but I am reluctant to tell people to spend money without actually being certain they will see a difference.
Cheers
Paul
