I think that (nearly?) all of the v2beta bugs related to sync'ing were due to the Jiffies issue, that Hijack fixes.

I have used only v2beta to populate my current four players, and all went nice and smooth, in one big 18-22GB gulp each time.

The only grief I've ever had was in trying to upgrade from 1.03 to v2beta with music ALREADY installed. Ugh.. major database conversion hassles, definitely not worth a repeat by me or anyone.

Cheers
