I had a lot of problem with the plextor 708A trying to get it to perform well on 700Mhz high end IBM machine. It’s a bit old but a very high end computer system for multidmedia. I had no problem getting the drive to play DVD well even at 1280x1024 resolution on number nine video card 16MB (S3 Savage chip). DMA was handled properly under Windows 98SE.
When I run Win2000 it’s bad, slow, jerky and distorted sounds even though DMA is shown as enabled in the device manager->IDE channle->advanced setting. So I wasted nearly one day to get it to perform decently, but still not to satisfaction. Here are what I did
- Place the drive on a separate IDE channel in Ultra DMA mode, no competition at all for bandwidth
- Bring the resolution of the screen down to 1024x768, 32 bits colours or keep it at 1280x1024 but only 16 bits colours. The smoothest performance is at 800x600 and 32 bits colours. Well, that’s my only dissatisfaction. I cannot have max resolution and good performance in video image quality and smooth playback.
The two actions above make a lot of difference on Win2000. So if you have similar problem, try these. I suppose only old computer with 700Mhz CPU or less would have problem. The manufacturer mentions minimum 800MHz CPU, that says something. I think they mean 1200Mhz for decent performance. You can surely use Win98SE and be sure that you get better performance but then you cannot do anything else while DVD is playing.
