    Okey kids, bare with me, I'm now to this whole thing...
    I got my first DVD-rom drive today (Toshiba) and it came with Power DVD. I installed it and ran trying out my first DVD movie playback...
    And it failed.

    Vince,
    Most likely your video card drivers need updating, maybe even the DirectX version also.

    Vince,
    software decoders work by creating an overlay surface using your video card's available memory. that surface is always in 24 bits per pixel. so Powerdvd needs ~1.5MB (960x540x24 bits) of video ram just to do the overlay, in addition to any video memory it is using to draw the desktop and any windows etc. what is likely happening to you is that your video card doesn't have enough memory to draw the desktop at 1280x1024x32 and have enough left over to do the overlay as well. 16-bit color takes a lot less memory to display and when using it you have enough left to draw the overlay as well.
    though as Cliff said, it probably wouldn't hurt to make sure you have the latest video drivers for your card (what card do you have?) and latest version of directx

    Vince,
    IIRC, that card only has 4 or 6mb of video memory on it, so the reason I stated above is exactly why you can't run at 1280x1024x32 and watch dvds. If you're looking for a cheap upgrade, a $20 Nvidia Riva TNT based card w/16mb ram (comes in AGP or PCI) would be perfect

    I don't think a PCI TNT card will work!! I Had a Viper 550 PCI and it didn't support DVD playback

    Really Brent? I know my AGP TNT card worked ok, so I'm surprised that the PCI one doesn't. I agree that this sounds like a memory issue here, so getting at least a 16Mb card is a good idea.

    I have a two-year old Diamond Viper V770 32MB AGP card and it works great -- plays back DVDs at 1024 x 768. [​IMG]

    If you do just work on your PC and do not play any extensive 3d games I would recommend a Matrox G400 or G450. They have the best visual quality out there and have a nice feature called dual head where you can connect a second monitor on the card or even connect a TV if you do not have a second monitor. I have a G400 for 2 years now and am not planning to change it. As Matrox just started to sell the G550 you should get the card for under 50$.
    DVD playback is decent if you have a CPU with more than 500 MHz.
    BTW they have either 32 or 16 MB of RAM.
