Hmm, maybe that is why no one else responded to this then :). So the player seems to obey the setting of 600?

The last time I tried a higher setting I had a MKII, and I think I was using 1.02 emplode/player software.

This was the first time I tried this since then.... now I have 2.00 and a MKIIa (my player was replaced due to a mainboard problem).

I doubt the longer setting has anything to do with going from a MKII to a MKIIa (?), so maybe this was a feature of 1.03 (although I don't recall seeing anything about that in the release notes for 1.03).
