Paspatout

Hello all, I'm new around here and new to android tablets so please forgive me if this topic has been done to death already, or if I'm in the wrong bit of the forum.

The problem is that I've aquired a new 7" Tabtronics A10 M009SC tablet with the following spec :-

CPU : A10 1.2 GHz
Graphics Processor : Mali 400 MHz
Touchscreen : 5 point multi touch capacitive
resolution 800 x 480
Operating System : Android 2.3 GINGERBREAD
Memory : 512mb DDR II / 4gb NAND

It's generally very good but I'm very dissapointed by the audio being way out of sync on Iplayer and other tv streaming apps. I've tried various releases of Flash Player up to 11.1 but without success.
Is there anything that can be done about this or is the spec just not up to the job?

Thanks for any suggestions.
