Which program for easy cutting?



I use a Panasonic DVD-Recorder with DVD-RW and DVD-RAM as media (no harddrive!). When i want to keep a movie, i take the disc to my PC and use Nero to copy the finalized dvd (in the case of DVD-RW), or Nero Vision Express (in the case of DVD-RAM) to create a “proper” DVD as DVD+R or DVD-R.

Now my question: Which program would you recommend for cutting to remove adverts und superflous recordings at beginning/end? I used to use Magix 4.5, but this doesn’t work reliably. Is there an easy-to-use cutting function in Nero? Or would anybody recommend a different program?
Thanks for any help!
