Select subtitle files and know wat kind of subs i can use. also hardcoding subtitles to video would be good feature

When converting to PS3 or XboX video format selecting subtitle file would be advised and possible. Also hardcoding subtitles into video would be usefull because in PS3 they can't be turned on/off on *.ts files. m2ts file type would be good and converting into this system with CUDA support would be great.
