All right, i own my own production company, so i tend to think im a more advanced user, so im hoping somone out there can help.

I have a 450mb MPEG 1 format file that i downloaded off winmx one day, the file seams to be intact, execpt at the 6minute mark of the video. When i try to ethire copy, or move the file it locks up windows, when i try to re-encode it, it locks up windows, when i try using programs like VCD Gear, and TMPGenc to demultiplex it, it locks up my computer. THE VIDEO works tho.. execpt when i play it to the 6minute mark it of course locks up the computer if i play up to the 6minute mark move the slider over the 6minute mark it will resume without locking up. If i try to delete the mpeg file it locks up my computer.. so What are my options i would like to fix the mpeg but if not that i guess i will have to settle for. Would Appreaciate anyones help.
