I'm using ulead dvd movie factory 6. I ripped the subtitles using subrip, but on the 2end dvd, the timing is off by a few seconds, but if I try and use ulead without uploading the dvd files, it gets lost. also, whenever I upload 2 dvds to 2 dvd subtitles, they get mixed up. 2 subtitles on 1 dvd while its playing. should I upload the dvds with ulead and make the menu, and then edit it with a different software to imbed the subtitles? also, how do I alter the subtitles to be on queue, since the 2end one is off by a few second? would deeply appreciate some help.
