480p Youtube Resolution on 480*854 devices (FWVGA)

I have an HTC Desire 610. I just flashed and unofficial build of Slimkat (you can find it here: http://forum.xda-developers.com/desi...d-9-0-t3149308). After I flashed it, i realized on the stock YouTube app, there was no 480p option in Youtube (i was watching an HD vid, 1080p on my desktop, but it was on my phone). The only res that showed up was 360p 240p 144p and auto. Back on sense, i had 480p, so can anyone give me suggestions on how to fix this problem?
BTW, i chnaged the buil.prop to 4.4.2 insted of 4.4.4 but it didnt make a difference.
Any help would be greatly appreciated.
Thx
