Mediatek (GE?) Player & vbr mp3 audio delay

erdie · 14th June 2004, 22:34

Just tested the following with my Gran Prix 504 (Mediatek MT1389GE):

loaded an AVI (with perfect A/V sync) with VBR/ABR mp3 into Nandub, Interleaving, Delay Audio Track by: 300ms

OK, the AVI is desync now, 300ms are pretty obvious.
At least on my PC it is.

Checked it on the HW player - nothing, audio still perfectly in sync.

Next test: 1000ms, horribly desync on the PC
Not really that much desync on the HW player (say 200ms maybe).

Using CBR audio and everything is as it's supposed to be.

Can anyone confirm this for Mediatek MT1389DE chips as well?
