Using Dr. Divx and what else to cut commercials?

[airedale]

I have some HD Streams (.ts files) that I have recorded. I am now looking to get the commercials out of the files.

I know how to cut off the begining and endings of them, but how about chunks in the middle?

Any suggestions?

Thanks!

Avisynth. trim out the commercials and then encode.
