I've a 8x USB 2.0 DVD hook up to my 475mhz notebook computer. When I play the movie the screen sometimes flickering. Does anyone know why? Are there any fixes for this problem? Please post some tips. Thanks!!!
It sounds like you have a very budget system. That is a K6-2 475. It uses a 95Mhz bus and has very bad memory scores. The Blade graphics card is about the worst one out there. WinDVD also has version 3.1 out now. You can get 3.0 free at most download sites. Unless you added USB 2.0 to your laptop, it is dropping your nice USB 2.0 DVD drive back down to USB 1.1. This will cut the performance considerably.
Using a GeForce2 GTS on an AthlonXP 1600+ with 256MB DDR tweeked to the max and WinDVD 3.1 I get perfect playback. The CPU utalisation runs about 30%. If the Blade is not as good at playback you will definately start dropping frames at 475MHz.
Now if you had a dedicated DVD decoder card (probably not too many that would fit in your laptop) you would run fine. These things only required a Pentium 133. Most laptops are not very upgradable and finding parts that fit in those odd-ball expansion slots (if the system even has one) is pretty tough.
I think it is time to upgrade. You can get a nice laptop for just over $1000.
