The project I've been working on, and that has given me the replaced clips problems recently in 10e, currently has 1096 items in the project media, and about 15 tracks. It's a mixture of SD DV and audio. I worked on earlier, equally complex versions of this project in Vegas 6, 7 and 8, and copied and pasted to my heart's content without problems.

>> BTW, really enjoyed the Andaman Sea video and looking forward to watching the others. I thought the narration turned out especially well, did you do it yourself? <<

Thanks. New episode every Tuesday here (pls excuse shameless plug). Yes, I did the V/O myself. I think I get a bit tiresome to listen to after an hour or so. Would be nice to maybe alternate chapters with a female V/O to give the viewer a break.
