TMPGenc MPEG Editor : Audio Sync problem

[Serville]

I recorded some satellite TV program into MPEG2, and I want to cut out all the ads, which can amount to 30-40% of the recorded filesize.
The problem is, after editing I always have audio sync problem.
Using TMPGenc, MPEG tools --> audio sync problem.
Using TMPGenc MPEG Editor --> still audio sync problem.
I like the interface of TMPGenc MPEG editor, which is simple to use, but the severe audio sync problem makes me mad.

What can I do ?
Is this TMPGenc MPEG Editor's problem or what ?

Any other easy MPEG2 editor program which is more reliable, easy to use? It has to be capable of editing/cutting multiple selections at once.

oh well, after reading several comments people suggest TDA to cut commercials directly.
I tried it just now, and suddenly......another new problem I've never met before........."THE VIDEO GOP IS TOO LONG". Now what else is this ?
Other programs like NeroVision, and Roxio never complaint about my MPEG.

As a real beginner, this whole thing about "capturing and converting to DVD" thing is certainly very complicated for me.
