Thanks for looking into this. I finally figured out how to change the burn speed and changed it to 1x, and even used Imgburn. But I still have the same problem. The copied bluray still jerks and jumps. So I don't think it is a burn speed problem. What else could it be?

Imgburn will tell you what speeds are supported for the specific media and drive combo you are using (as determined by the table in the drive's firmware). Based on my own experience, if you go outside of that range, even say
1x, if
2x is the lowest supported speed, you MAY have issues because then the drive will use generic writing strategy rather than the what is specifically stored in its table for the specific media you are using. Of course you cannot exceed the maximum speed as set for that media, but you can go slower even to speeds not specifically supported. If the lowest speed shown is 2x, try that rather than 1x and see if that works.
Another issue is some drives do not handle dual layer BD-R's all that well for some media. Again, my own experience .. have a Sony BDP-S6500 which often chokes at the layer break, but I recently bought a BDP-S6700 and that plays all BD-R DLs just fine that were a problem with the 6500 (had similar issue with a friend's S6500 as well, so it was not due to bad player). If you have access to another player, you might want to see if the stuttering is still present.
