When I upload my mp4 files into the onboard memory on my G2x, they play with no problem. But ony my SD card, it doesn't. It keeps giving me "Format not supported" error. Same file it was played before. Also, when I transfer that file back to my laptop, the laptop gives me file not supported. Does the phone convert the file own its own? I use handbrake to convert my movies to mp4 file. Does android need a specific convert settings to play? Thanks
