[LAU] replaying prepared backing tracks

Hi guys, For some time I have been preparing backing tracks using Ardour 2/3 etc. Mixing down to mp3 for live performance. We are having reliability problems during playback. I have tried my netbook (Tosh nb200) my tablet (Samsung 10.1) & an ipad(not to hand, not mine)  The playback fails at random point (if at at) & will often then replay satisfactorily. The mp3s are created on a 64bit machine using Ubuntu studio as the base setup & converted to mp3 in Audacity on the same machine. I am lead to the belief that it is not the playback machine athough not completely due to the randomness.  My thoughts are:-  mp3 conversion  mp3.  64bit conversion Doesn't need to be mp3. flaac would be my choice. it does need to be fast loading with random access (tablet is ideal). Don't mind spending money. Steve Sent from Samsung tablet
