DVD freezing

I have had the freezing problem on Sony, Insignia, Cyberhome, HP computer DVD drives, etc.
Based upon very numerous incidents (believe me, I mean hundreds) the problem occurs most frequently after about the first hour as the track moves outward from the hub (and velocity per 360 degree turning increases).(Recording is from the hub out, not from the outer edge in towards the hub). An engineer suggested that the increasing velocity creates the greater possibility of the reader "missing" a data fragment which, in turn, "freezes" the image presently in the buffer. It may "recover"
and move data along again but will probably "freeze" again.
The following definitely helps but does not always work:: Keep the track "tight" by recording actual
running time NOT longer than 30% of the maximum capacity
permitted by the selected speed. Example: On a Sony RDR GX7, I record not more than 60 mins actual time at LP speed
which, on this machine, permits a maximum capacity of 180 minutes using LP. Based on literally hundreds of DVD recordings, I can say positively that the above approach HELPS
limit the problem but it DOES NOT totally eliminate it.
I REALLY WOULD LIKE TO HEAR FROM OTHERS, PARTICULARLY PROS, WHO HAVE INFORMATION ON THIS SUBJECT. Even reduced, the problem is irritting.
