Panasonic DMR-E85H Chapters question ....

Hi all ....

I purchased one of these fabulous machine yesterday , and tried some HD to
disc burning from last nights T.V . I time recorded the RAGE Top 20 to Hard
Drive with no problems . I then partial erased with no problems to get rid
of the end bits ..

But what I don't understand is when I've gone back in and inserted chapters
(at the beginning of the songs) . It looks and works as it should off the
hard drive but when I burnt to disc I found playing the disc that the
chapters are in places I didn't put them at . Can anyone tell me (that has
one of these machines or that has had this problem themselves) what I've
done wrong ...

Thanks in advance ...   c];-)
