Hello

I bought a Philips smart TV model47pfl4007h/12
How can you add subtitles on an USB so the tv can read it. First of all i tried to add subs to an avi file with aviaddXsubs. But the tv isn't able to read it because it's a Divx.
So can you tell me how i can solve this problem? Maybe another program that i can use or how i can add subs to my usb so the tv is able to read them.
