Choppy DVD Playback

[Maxfreak]

Advice please,

I have an ATI Radeon 64 MB DDR graphics board and a T-bird 1.4ghz processor. I thought this would be ample processing to play back DVD's however after installing my Toshiba 16x DVD drive I still get a choppy movie on playback. Do I "need" a decoder card or maybe there is a work around that I am missing. Thanks

Your Radeon is the best hardware decoder out there, you just need to go into the Device Manager & enable DMA for your DVD drive...that should take care of it.

That is what I am saying and I don't understand what is wrong. Thanks for the tip but I already enabled DMA for that IDE device. I even unchained it from my other CD-Rom and made it the primary master on the primary IDE controller. Still no luck. The Drivers are all up to date on the dvd, graphics card, and motherboard.....I am out of ideas that is why I turned to the board.

ATI Radeon is not a hardware DVD decoder. It has things like motion compensation, but it is not a full hardware decoder.

As for the Choppy DVD's, what OS, and what player are you using to play the DVD's?

 

[wdb1966]

DirectX 8.0a and the Capture Update for DirectX 8x installed?

What OS?

BTW,

ATI DVD player is a hardware+software combo, requiring only a P233.



DXR3 from Creative (same as the Hollywood) is also a hardware/software combo requiring only a P166.

Not much difference between them...other than current drivers from ATI...Creative's post '98se drivers are all BETA, no official updated drivers

With modern processors and Hardware motion compensation like the Radeon has, you won't need a full Decoder card.

But, I had someone with the same setup but a 1.2ghz Athlon and he could not get the ATI DVD player to work properly. Is that what you are using, if so, see if you can get hold of WinDVD or Power DVD, he had success with Power DVD but I lean more towards WinDVD.

Are you OC'ing? If you are it could be the FSB not being synchronous. Try a standard setting like 100 or 133 FSB's.

The OS is most imporant here i think. I had an ATI rage fury under win98 and it played dvds great. Now i have a ATI AIW Radeon and the first couple minutes of some dvds is choppy under winME. it gets better after a few minutes, not sure why maybe the drive warms up or something. I need to switch over to win2k to test out my theory.

I'm getting my 1.4 tbird today so i expect a reinstall is in my near future

edit: btw i have a 6x slot loading pioneer dvd drive and i have loved it. since dvd movies only play at 1x the speed of your drive shouldnt make much difference.
