Toby has recently done some work to make the Seek Tool more reliable in the face of bogus track durations. Don't know if it'll fix your problems, though.

As to your wishlist item: Tricky. The disks are mounted read-only, and there's not enough space in persistent storage to keep VBR headers for (potentially) every track on the player.

The correct solution would be to fix the VBR headers up in-place, on the empeg, when the disks were mounted read-write (i.e. during a sync).

Hmmm, maybe we can actually do this? Probably won't make it into v2.0, though.
