G400 DH - DVD playback jumpy after CPU upgrade

[robconvery]

Previously I was running an Athlon 700Mhz with 512MB ram. 2 HDD/DVD-ROM, all working in PIO mode (thats all the MB supported). Graphics card - Matrox G400, setup with DVDMax on second output. When playing DVD's the machine just about managed to play them. I rarely ever had a jitter during playback, once in 3/4/5 DVDs. As soon as the machine was doing anything else it then would start jumping majorly.

I have now upgraded to a Barton 2500+ with 512MB ram. The motherboard now runs in UDMA mode 5 along with the DVD-Rom (UDMA 3). I have reinstalled the OS so no crap from the old system was around. I have made sure i have all the latest
M/B, Graphics card etc drivers but when i am playing a DVD in PowerDVD its on the limit and there are jumps every 10/15 seconds, the CPU is up at 80-100% all the time.

Any idea what could cause this. Obviously the graphics card is not majorly hot but surely all that extra CPU is not wasted when using the G400?

Full specs on the new system please.
Reinstalled "the OS"? What OS?

What G400 Drivers are you using? Have you installed all the drivers for your MB on the off chance that its a VIA MB?

Like mmp said, make sure you've got the latest motherboard drivers.
Also, check your mobo BIOS, and set the AGP aperture to at least 128, and check to be sure you have 'assign IRQ to VGA' enabled.

How are your drives wired up? The hard drives should be on one channel, the DVD should be the master on the second channel.

[robconvery]

yup HDD on channel 1 and DVD writer on the other channel

Are you running the SAME OS and SP as before? Are you running the SAME DVD playback s/w (and version) as before? Are you running at the SAME color depth and resolution as before? Have you run PowerDVD's tests, and have you set the DVD drive to DMA in the WXP Control Panel, if present (not just what the BIOS says)?

For what it's worth, I've found WinDVD 4 works better on W2000 than PowerDVD 4, but PowerDVD 4 works better under W98 than WinDVD 4. Go figure. Not sure this is relevant, but it might point somewhere for a soln.

And just out of curiosity, what is the product code on the G400? Does this new mobo require 1.5V or 0.8V AGP cards only? Is there a setting for AGP speed in the BIOS? Is the video card sharing an IRQ with anything else (this isn't supposed to matter, but sometimes it does).

[Mcollector]

And yet another oh yeah. What version of DirectX, before and after?

[robconvery]

RE AGP support the manual says

"This motherboard has an AGP slot that supports 1.5V AGP card. AGP is an interfacing specification designed to display 3D images. It provides a specialized 66Mhz, 32-bit channel to allow the graphic controller to directly access the master memory, and supports 4X and 8X speeds."

AGP Settings in bios = 4x
Video card sharing IRQ = Yes - With Ethernet Adapter

DirectX version 9.0c before and after

[Wombat]

ew. You don't really want the video card sharing an IRQ with anything. Move the ethernet card to another PCI slot.

Same OS/SP
Same DVD playerback and version (tried newer as well)
Same Resolution & colour depth

DVD-Drive with DMA running

IRQ changed of network card and still no improvement

Grrr this is driving me to putting the G400 in the bin

[Mcollector]

hmmm... Maybe there is an issue with your new mobo and the G400. Does your G400 have a "4" in the model code after the G4+? e.g., G4+M4DH32G, not G4+MDH32G? Maybe the G400 just plain doesn't work well with the newer CPU/mobo/DVD s/w combo. Tried any other DVD playback s/w? What's new in your system, just the CPU/mobo/RAM? Any high activity on aonther subsystem at the same time, like the NIC (though I'd think the system is more than fast enough)? Tried lower color depth/resoultion for DVD playback, like 800x600x16? If it can't do 800x600x16, something is most definitely wrong (stating the obvious).
