I finally got my BluRay DVD to burn after a series of errors kept popping up. I still don't know why I was getting these errors, since I made no changes to my PC. I continued to use the trial version of the editor that corrected unwanted shifts in the text timeline. This is scheduled for a correction in the next release. The AVI file I moved to the timeline did not install correctly, but the file that produced the errors somehow got installed on the timeline, despite the numerous errors generated when I tried to move it there. I will chalk this up to some kind of random error that hopefully will not reappear.
Although I was able to burn my BluRay DVD, the chapters I installed (about 20) were not available on my Samsung BD-C5500 Blue Ray Player connected to my Plasma TV. This is an old issue with my BluRay burnings, one I submitted a while back to Support. They could not reproduce it at their end, so it leaves me with a less than fully performable BluRay disc. Whenever I select Chapters off the lead menu, I see the first 3 on the TV. I cannot then select more than these 3 using the arrow keys which just cycle around the first 3. I am left with the quandry as to what is broken here. Is it the AVS software or is something wrong with my Samsung. Strangely, this phenomenon does not appear with the non-BluRay DVD's I have created. Those chapters work fine.
I am curious if anyone else has had this problem.
