Nero recode playback problems

hello, I need help with nero recode. Some movies will playback fine on my standalone and some have problems. I use sony dvd-r and have also tried other media that are not crappy. when I use dvdshrink, the same movies that wont playback correctly on recode play just fine. I have installed all of the latest updates for recode but no luck there.standalone player is a panasonic ht930 that excepts all formats of media.dvd-rw is maddog and liteon.

What is the brand of media you are using? Run Nero CDSPEED and run a disc quality scan and post the results here.
