Replication worries

In preparing for replication, I burned several DVD9-R test discs before sending my project off to the replicator. I own 7 DVD players from 4 manufacturers that I use to test discs for playback errors. On 6 of my machines, I get flawless performance. One of my machines will freeze every time in the same place on each test disc. That place happens to be 1.5 minutes after the programmed layer break point. It is therefore close to the outer edge of the DVD9. The total size of my movie and menu content is about 7.8GB. The video was encoded at 5 mbps CBR. There are DTS and AC3 5.1 audio streams. I authored in the latest DVDSP version with a G5 Quad.
For replication I prepared two DVD5's, one with layer 0's DDP 2.0 files and one with layer 1's DDP files. I sent backups of both discs, too.
My deduction is that the one problem deck isn't dealing with the breakpoint on a DVD-R because of a malfunction in either reading the break point or just dealing with stuff at the out edges of the disk.
Should I be worried that 1 out of 7 players are not going to like my replicated discs?

I wouldn't be concerned. I would however get check discs back from the replicator before continuing with the run. If it makes you feel better, there's is a guy named Trai Forrester that does verification before and/or after replication to make sure your job is up to spec.

DVD-R DL tend to have playback issues on some DVD players around the layer break. Usually it happens a little bit closer to the layer break than 1.5 minutes after it though. I don't think you have much to worry about. I would check the bitrate of the video file you are having a problem with and see if there are any spikes that could be causing an issue.

Luke,
It looks like Bitrate viewer isn't for Mac. Am I right?
I used 5mbps CBR w/ 5.1 AC3 and DTS.
I must say that the more I think about, using a $39 superdrive to create a master for a 2500-5000 replication run on a movie that cost $400K to make does seem dicey on its face.
