hello. long time reader, first time poster. i have a powerpc g5 running at 2.1ghz with 2.5 gb ddr2. now my question is about increasing the speed of my old system, which i know is a daft question but hear me out. i can play some 720p but not all. im looking to play 720p mkv files like highres television shows i would get off TPB [through VLC]. but the playback is just the slightest bit too slow. like the SLIGHTEST bit, not pixel-ly, it just hangs on to every other frame a fraction of a second too long. im pretty sure if i had a 2.11ghz it would be smooth. im not running any other programs while trying to get a smoother playback, even closed peerguardian to get that extra 5%. im not overly technical but i can certainly follow any instructive tips given. im not looking for any costly upgrades or add-ons, but more tips to improve the playback just a touch. maybe VLC settings or a better player for mkv files [which are the only available for new 720p television. im not looking to play bluray rips over brrips, just a small boost to help the mkv files and a couple of the chunkier avi/mp4..etc. any help would be greatly appreciated.
