View Full Version : Improvements in DVD playback for GFFX

07-16-03, 09:45 PM
Hi all

I currently have a Leadtek GF4 Ti4400 and a Realmagic Hollywood+ DVD card. I have found that there are many DVDs that the Hollywood+ just can't play, so I resort to using WinDVD for lots of DVDs (and the fact that I don't have to muck around with the pass through cable which degrades 2D quality quite substantially).

Although this means I can play the DVDs no troubles, the quality is quite poor when compared to the H+. I am wondering if anyone has some first hand experience in comparing the DVD playback quality of the GF4 Ti and the GFFX cards. I am looking forward to retiring the H+ card, so high quality DVD playback is a must.

Also, has anyone compared the FX series to the Radeon series?

I've just used software mode on PowerDVD on all video cards I've owned from both NVIDIA and ATI. I've found this to work the best when viewing all my DVDs including anime.

same here...i'm too cheap to buy a better dvd player with hardware acceleration.

And with today's CPUs it's pointless to have a separate decoder card. I remember reading something where a computer with a card was compared to software and only like 1 in 10 people noticed a difference.

Thanks for the replies so far. As for those 1 in 10 who notice the difference - I guess you can be me a 'one'. I downloaded a trial version of PowerDVD, and the quality was not noticably different from my old version of WinDVD, and still not as good as the Hollywood+ card.

Keep in mind that I only have a GF4 Ti, which only has motion compensation but no hardware support for iDCT. I tried PowerDVD both with and without hardware acceleration and there wasn't much difference. Is it supposed to do software iDCT in the absence of hardware support?

I thought the GF4 TI series had hardware support for iDCT, but guess not.

Certainly the GeForce4MX series does. http://www.nvidia.com/view.asp?PAGE=geforce4 Its under VPE

now check this out...

In addition to its 3D capabilities, the GeForce4 MX is the only Nvidia card to have iDCT support for DVD decoding--something that ATI cards have had for a while. This feature was specifically added to the MX line of cards, because these are more likely to go in slower PCs, where it can be useful to take a load off the CPU.

So the cheaper GF4MX series has hardware support for iDCT, but not the GF4Ti series. Yeah that makes sense. :retard:

Yup sbp, that's the case. Now, I guess the remaining question is whether or not the FX series has the same VPE (or better) as the GF4 MX.

All FX GPUs have VPE 2.0 according to Nvidia's website. Try using NVDVD 2.55 or higher with Detonator 44.03 or later with your Ti4200. Those drivers improved the Motion Compensation Size from 8 bit to 16 bit, quality is definately up compared to the previous 30.82 and lower drivers.
