hi guys thanks for replies!
senu: il try defragmenting and see if that helps. sorry about the pic motion reply ...to capture im using sony vegas 7 at the moment. oh and it was the same problem as that other thread. just didnt get no replies on that

, maybe i wasnt too clear in that
rhubarbe: yep the xp 2600 is overclocked at the highest i can get it. stock speed is about 1.8ghz lol. been running it overclocked since day 1, about 4 years now i think, maybe more.
on the whole the pc is due a good upgrade. probably going to go for an e4400 and ramp it up to 3ghz+ - its a killer!...and cheap lol
oh and just as a side note, the m2t files play flawlessly on the ps3 (merged all the files together to give 3.53gb file, only 19minutes lol). is there a recognised file limit of 4gb on the ps3, think i read something about that...sorry to go off topic there...
thanks guys,
simba
