I have four mpeg files that I would like to join. But when I tried to open first mpeg file I got following error in VirtualDub 1.3c

"VirtualDub Error MPEG Import Filter: packet sync error"

I also try using iFilmEdit and got this error message

"iFilmEdit Error:6007 incorrect system stram in source file"

When I try to use tmpgenc12a no error message appears but it would join the mpeg correctly.

Any help would be appreciated. Thank you, -Rauf
