Problems when playing videos

First i have to say. that i am from austria, and so my English maybe isnt perfect.



I have two problems when I try to watch videos, video-CDs or DVDs on my PC:



1. Videos are played too fast and not fluid:

This problem occures always when I try to play video-CDs and DVDs. In some cases it also occures when I try to play video- or audio-files from my HDD: At the beginning the speed is normal, but after about 1-2 seconds, the video starts get faster and doesnt run fluid anymore. Sometimes there is also a strange sound, when this acceleration starts. Then the sound gets faster and somtimes interrupted and somtimes the sound comületely stops. I have this problem as long as I have my new PC, but I only find it really annoying since a few days, because I have bought a 5.1 speaker-system for my PC, and also want to use it for DVDs.




2. Windows Media Player doesnt play internet-video-streams:

Since yeasterday I also cannot watch internet-video-streams w/ wmplayer: After the loading-screen disappeared, the video-window stays black. On some sites it says, the I should wait for buffering, but this only takes a few seconds, and I have waited more than half a minute. It cannot be a problem of a specific internet-site, because I tried it on different sites, but it worked on none of them. I dont have that problem w/ different video-players.

I have already enabled DMA on all my drives. I dont think, that the DVD-drive is the problem, because this also happens when I play VCDs on my CD-RW drive or sometimes even when I play Video-Files from the HDD. It also happens when I play any Audio-Files except .wav (I tried .mp3 and .ogg (UT2003)) from my HDD. I will trie Audio-CDs, but my DVD-Drive doesnt work at all now, and I have to get the bill from someone, because I got it as a present. My CD-RW-drive also has reading-problems (burning works), but there is no warrantie anymore on it.

I have the newest nForce2 driver.

DMA is enabled. It is set for all drives in the device manager since months, and if I wouldnt have DMA, Windows would automatically disable it when I reboot. I also have over 40 MB/s transfer rate in HD Tach. If DMA wouldnt be enabled, the maximum possible transfer rate would be 16.6 MB/s (PIO mode 4).

Maybe nForce2 doesnt use bus-mastering for DMA.

I have downloaded the codecpacks NIMO and SLD, but this also didnt change anything.

I had an "abstract error" however, when I first played the Star Wars Episode II DVD w/ the Zoom Player (zplayer.exe), which was included in the SLD-pack. After the error, the player continued to play the DVD. I started playing the DVD two times after that, but the error didnt return. I aslo played a normal .avi files w/ this player, but it also didnt report an error w/ this file.
