DVDA won't burn hybrid DVD's - the only folders that can be in the prepare folder are AUDIO_TS and VIDEO_TS - as long as those are the only things, then you should be able to click on burn and DVDA will reburn the project.
As always Scott, quick and informative...I should be giving you a free copy of the final print...if it wouldn't bore you to death.
If you noticed a post I made a bit ago about flashes between chapters (when selecting >>) I've found it to only occur on my Sony DVP-NS315 and not on virtually every other player I've gotten my hands on at Best Buy.
