[QUOTE=Whappo;2581778]The problem with most linux distro’s is the video card drivers. So, depending on which card you have (AMD or Nvida) check over at Phoronix for driver benchmarks. There are some open source drivers and also some proprietary drivers to try. You don’t give any hardware specs so no telling if it’s memory, cpu, or video card related. Also Ubuntu doesn’t come with a lot of codecs for audio/video, did you install any? Linux Mint is a bit more user friendly where multimedia tasks are concerned. What program are you using for the conversion? Which browser do you use?[/QUOTE]
I’m using avidemux, I have an nvidia 8600 GTS, 4GB RAM, 2.4 Ghz 64 bit AMD CPU. anything else you need? I DID fix the problem though, letting converter run on one CPU core, leaving the other free for other tasks!
