wrong mpeg1 stream whem using vcdeasy?

[SikGemini]

hello all,
when i try to add a mpg file that has been coverted from .dat to .mpg using vcd gear, i get a error message about error in mpeg1 stream or someting when it is adding and scanning the file. it think it is to do with the wrong format or something, and desperately need a program that will check my mpg files, and if needed, covert them to the correct format so that vcdeasy will accept them.
anybody with suggestions could you post them please.
thanx.
