hi guyz, i'm new here, so forgive mi if i have made any mistakes. i've got a question abt the software dv tool v0.53. i am trying to split my mpeg file (1.6Gb) with dv tool, into 3 parts. i can't seem to click onto the 'sys header' box, resulting in a screwing up of the splitted parts. can anyone tell mi where i've gone wrong? i kept trying, but i can't juz seem to do it. am i missing something? or is there a better software?
