mpegplayer A/V sync - please report experiences
linuxstb:
Older versions of loader2 do not correcly initialise the co-processor (COP) when starting Rockbox - so mpegplayer can't make use of the COP, which is why you're getting bad performance.
Either upgrade to the very latest version of loader2, or use the official Rockbox bootloader.

I'm trying to play the same file on 5.5g 30gb ipod video, but I'm getting 10-12 fps max. The sound seems to be in sync when skip frames is enabled.
I use Rockbox Bootloader to start Rockbox. Also, that file doesn't even want to play unless I rename it to .m2v and open it via "open with" menu. The sound is still present in the .m2v file.
RockBox Version: r14616-070905
