Broken mpeg2 fixer?

[manthing]

gang,

one of my mpeg2 files seems to be broken.

when the mpeg2 is played, it plays through the "broken" point, though there is an obvious visual and audio "crack".

can't seem to reencode the file. nor cut before & after the point.

what tool will allow me to repair the mpeg2 file?

ta in advance.

oops forgot to mention that i used "mpeg video wizard dvd" to try cutting before & after. but no luck.

i used tmpgenc mpeg editor to cut away the broken section. lost a few frames. ah well.

but i could still use some pointers as to what's the best tool/method to fix "lost frames".
