Ts and Mkv files - bad frames - repair help?

Is there any way to repair bad frames of an MKv or TS file, rather than eliminating the bad frames via a program like meteorite?

i tried virtualdub, and that program each time used says that it has stopped and working and to close the program.

Thank you in advance.

I have 48 videos of sports broadcasts that Id like to fix so theres no constant pixellation at some points of playback.
