Video files recorded on my sgs2 have the file extension mp4 but wont play on my sony bravia tv or via my sumvision cyclone mkv2 media player. They do however play on my windows 7 laptop.
When playing a video on the sgs2 you can get more info by tapping menu/details. This tells me the format is 3gpp. I believe 3gpp forms a simple wrapper around the mp4 file and suspect this is the element my other devices can't handle.
If I copy the files to my laptop and convert them to mp4 using [RZ Video Converter] program then copy them back to my sgs2... They now play fine on all my devices including the sgs2.
I would dearly love to play my movies on the tv via wifi without first having to convert them. Can anyone help?
