Here's my DVBC cable file. It might help, it might not.
I'm using DVBViewer so you might have to tweak it but it should give you a clue or a starting point.
The information Nozzer is giving you should be takne into account, it's probably far more accurate. Just asking the same question twice is unlikely to win you much help.
Note: this was an ini file but the uploader made me change it to a txt.
I hope it's of some help.
