High CPU Time using PowerDVD

[quriousman]

When I use PowerDVD to play a DVD on my P3 400MHz computer, the CPU Time is 100%! and the picture are not smooth ...
But if I use ASUSDVD, the CPU time is about 70% and the picture is smooth ..
What's the problem ?
What setting on PowerDVD should I change ?

Thanks!

I'm under the impression that ASUSDVD is PowerDVD in disguise?

Seems a little high... Make Sure DMA is enable on your DVD drive.

Thanks for the replies ...

I've enabled the DMA.
The problem is why it's OK on ASUSDVD (not a well-known software) but it's not OK on PowerDVD ?
It must be software setting problem, not hardware problem ...

ASUS May be a smaller application

it also couldn't hurt to defrag your hard drive

What video card are you using. If it's an onboard solution and it's an Asus motherboard then the AsusDVD you have was optimized for your motherboards onboard solution most likely reducing it's CPU overhead, I can play DVD's on my machine (xp2100 Gf4ti4600) with software Dolby digital or DTS decoding at about 10-20% cpu use but my video card helps the DVD playback quite a bit.

thats a very smalll system huh? you may want to try to
defrag you system files as well, dont know what OS u
are using, but xp cant do it, you need diskeeper to do
that, and it only works on NT...

Just thought I'd also mention, direct from PowerDVD's website... IF you are decoding a dolby digital stream down to 2 channel audio... You are really pushing the minimums for the program in the first place, so yeah, 100% actually doesn't sound too unusual.
