The LAVF mpeg-ts/ps demuxer doesn't really seem to be too stable in order to give frame-exact seeking. It seems to work for some things, and fail at others. Basically the idea of indexing the packet borders for the needed IDR packets from which lavf parsing/decoding can be started seems to work rather well.

Of course, if possible it would be nice for this kind of stuff to be implemented in ffms2 itself, but this is a basic first step towards having cross-platform solutions for various files.
