Bump.
Also, I've found that the Handheld Sync Audio Filename rule DOES NOT follow the same "system" as RMCF, and seems to have some special handling built in. For example: If I use the [Name] field in my Audio Filename rule, and the [Name] contains any periods, it truncates the output filename at the first "dot" it encounters. RMCF doesn't. I found a few other oddball behaviors like this.
I was able to beat this into submission by manually replacing periods with underscores, but I'd love to know what special "invisible" rules it has implemented. I assume this is because the filesystems used by some handhelds (or perhaps just FAT) has special rules for filename validity. I'm syncing all of mine to just plain NTFS folders, though, so none of that fancy stuff is needed.
If it would be possible to have a checkbox to turn that stuff off and make it work just like RMCF, that would be fantastic. However, I'd be okay with a listing of things to watch out for. I've had to, up till now, figure it out trial and error style.
Which would be fine if it didn't take almost an hour for my handheld to sync, including 10-20 min of MC being totally hard-locked and frozen.
