*Sorry if this is in the wrong folder. I have a few video files on cd-r' which won't copy to the HDD. I get an error message part way through the copying (invalid ms-dos function or something). One file has an error at around 30mins (ie. video stops) but before and after that point it plays fine on my pc. What programs are there that will let me edit the file and maybe split it into 0-29mins, then 30-120mins? Any help/links much appreciated.
