  Grogster said  I'm just using the default setup, which is 640 x 480 @ 252MHz.
I would have thought that 252MHz was PLENTY fast enough for decoding MP3 data.
It would not be the first time I was wrong, though, if that is not actually the case!  

I'm going to try some more files tonight, but just changing to the 8GB uSD card, made a big improvement.


Only for you, I dug up my 2350B(A2) and set it to 640@252MHz
It plays just instantly without delays or cracks with standard PWM output.

My test tunes were "Crazy train" by Ozzy Osborne and "Staring through my rear view" by Tupac encoded with 192Kbit
