in my case it's not working,but tnx. (When i was trying to make boot usb stick for bios, program was making a boot device of my hard drive, also connected to usb, instead of usb stick) That Mpeg was on it.(H disk)
For generally playing damaged or incompletely downloaded videos, the best player is VLC, miles better than WMP. If VLC won't play it, nothing will. You have nothing to lose if you try it, or even keep it for the future.
Load your mpeg 1/2 in Vdub mpeg2
cut out the bad part and save the bad part as an uncompressed avi
load the bad part in Vdub mpeg2 and see if any filters help correct the problem (avi is easier to edit/work with than mpeg 1/2)
If you get the bad part looking better/corrected re-encode to the same specs as the original
join the two parts back together.
