I have Samsung Eternity and Samsung Mythic cell phones. What format should I render in to upload to these phones for playback? They say they support .mp3, .mp4/aac, .mp4/amr, .m4a, .3gp/amr, .3gp/acc, .wma, .mid and maybe .wmv and .rm . Elsewhere it tells me the resolution must be 320x240.
I've tried some .wmv files but it says unsupported resolution. Same with .mp4 files of several formats, although a few play with only various tiny colored squares showing.
Please help.
