Yep, I second the suggestion to load your music onto the player using the same software version you plan to run on it afterwards!

I'm using the beta11 version and I've copied over about 22 gigs. of MP3 music to my player so far, and it's basically working quite well for me.

I have seen a few small glitches, but nothing "show-stopping". (Occasionally, I'll drag an album folder over to the Emplode software to add it, but it won't actually add it. If I try a second time, it works.)

I understand the beta can give you problems if you try to add too much music at one time - but I've been careful to only synchronize 5 or 6 albums full of MP3s at a time. Works well for me that way, anyway, because I need to fix ID3 tags on lots of my stuff as I xfer it over.
