baka masyadong malaki ang eventual file size ng movie. WinXP cannot save to file sizes larger than 2 gigs for a single monolithic file or the temp file being generated prior to rendering is larger than 2 gigs. Try using greater compression or break apart the movie into smaller files. baka konti ram mo kaya tumaas ang cpu and pf usage mo. Better to have 4 gigs of ram (with /3GB switch engaged) when processing video. You can also try using WinXP64 to avoid the 2 gig file limit but that will mean possible hardware driver problems as well as software incompatibilities. YMMV.
