...what im looking to do is make it so that the button that looks like an arrow going into a verticle line makes the tivo just jump ahead 30 seconds in the recording instead of jumping to the next segment...

Start viewing a recording, then press the following keys on the remote:

Select
Play
Select
3
0
Select

You should hear 3 short dings. The "skip to tick mark" is now a "skip 30 secs" button. When in fast forward or reverse in a recording, it will still skip to the next (or previous) tick mark.
