I think the pause midway thru the disk is the read head refocusing and reversing to play the second half of the program. What I'm saying is that a DVD can only hold one hour of program from the inner "groove" to the outer then it has to reverse to play the second hour (outer to inner). I've gotten the artifacts you mention but only with dirty disks.
Use a high quality disk cleaning machine (like a Nitty Gritty) to clean-before-play. Finally, this machine draws a lot of current (blows the fuse in my Tice Micro-Block power conditioner) but feels only warm to the touch playing CD's (will try DVD next time).
