Video editing - Nero 8

Just treated myself to a new Pc with Win Vista and a TV tuner.
Using media centre I can record TV to my PC.
I want to remove the ads etc from the beginning, middle and end of the recorded program and burn to DVD, so I bought Nero 8.
Having spent many hours fiddling around I’m still none the wiser as to how to do this.
Using Nero Vision I managed to trim the ads prior to the start of the program, but then the audio was out of sync.
The manuals only explain what each function performs. I can’t find a ‘how to’ anywhere until I found this forum

Using my Panasonic hard-disk recorder it takes less than 5 mins to edit out all the ads. etc - It’s so easy.
Nero seems to be way over-complicated for such a simple task.

Can any kind soul point me in the right direction please

Thanks
Pete
