I do use these three tools:
- DV-Tool 0.49 ( I posted that one in the forum already)
superfast, can split to x parts with same size, splits also two language svcd streams (which tmpeg can't), freeware
no optical control; for splitting at a special scene you need to know the offset data.
- M2Edit Pro 5
expensive, slow, but with optical control; splits frame accurate; a lot of extra professional features
- Womble Mpeg2vcr 3.12
expensive, fast, with optical control; splits frame accurate; with some professional features (f.e. transitions)
small cute program
and some other ways ...
