ROBOTANK I've been having quite a bit of trouble with ReduxEncoder. At first I was experiencing the error noted below on Leopard ("illegal comparison or logical"). Now on Snow Leopard (10.6.1), the old problem is gone away, but new issues have popped up. First I tried converting an XviD AVI file to DVD. The conversion to the MPG file went fine, but it would not proceed past that point to authoring the DVD structure. Whether I selected burnable image, VIDEO_TS folder, or burned DVD, after the conversion was done, "Authoring DVD" (or something like that) would pop up for a about a second above the progress bar, then it would claim the process was finished, leaving only the MPG file. Next I tried converting an H.264 MP4 file. With MEncoder decoding, it ran for about 5 minutes, then claimed it was finished. The result was a 400 MB partial MPG file. Trying the same conversion with VLC decoding never got past the "Starting conversion" phase. I know that ReduxEncoder is a work in progress, but I do hope that it reaches a fairly stable and usable state in the near future. It looks promising in many respects and is free, so I'm optimistic that it will turn out to be a worthy successor to the venerable VisualHub.
