Hi I have a 3GS running 3.1.2 and using MiVtones...For some reason half of my videotones play but the other half dont.I Also have a 3G and they all played on that phone..I'm thinking it might be a resolution issue because it seems all the ones that play are a higher resolution than the ones that freeze or play with a bunch of green blocks.....any help would be greatly appreciated... TIA
