Klaus,
I don’t know if this answers your question, but have a look at CatDV Pro. While playing back the tape, the program will recognise all the shots either by time stamp or frame differences. You can record LowRes Quicktime movies with timecode and can create a batch cature list with T/C, description and lots of other info.

Hope this helps
