ES25 hesitation problems on recorded DVDs

Any suggestions for eliminating hesitations when playing back recorded DVDs on the ES25?

When recording DVDs from a Memorex MVD2022 DVD player connected to the ES25 with a Sima “Go DVD” converter box. Using TDK 8x DVD+R disks. Most copy with no hesitation problems, but about 20% of recorded disks are showing hestitation about every 4-5 minutes during playbacks.

Any ideas as to what may be causing this and how to eliminate? Thanks, Joe.

Any hestitation when the discs are played on another DVD Player? Sounds like a bad burn or media problems.
