Hello, I am using Fedora 12. I just upgraded from an nvidia geforce 6200LE 512MB to an nvidia geforce 8400GS 512MB ( PCI-X ). All video and sound "jumps" and is quite choppy. When I switch back to the 6200LE everything falls back into place. I decided to update to the latest nvidia driver and have the same issue. The 6200LE works fine, whereas the 8400GS has the sound and video issues. The card works fine in windows 7. It also seems to play youtube videos well in firefox ( Linux ). Any suggestions/solutions would be appreciated.
