Hi, I have not got an ipod touch but i am thinking to buy if it meets my need. I have got 1080p mkv moviels files I keep in an external hard drive attached to my internet router which can be accessed via ftp or samba, and a 3rd generation Apple TV. I want to stream mkv files with subtitles srt,sub etc. to my HD LED TV via airplay on ipod touch to apple tv. Is the processor of ipod touch latest gen enough to do this ?
