FW that supports HFS+ AND Mediasharing?

Hello guys. 

I bought a WNR3500L about a month ago but started outh with opensource firmware just this week. It took me one day to brick the router after fooling around with some stuff I had no clue about :) So I bought the USB-TTL cable and are now playing around with router again with no fear of bricking :) 

Anyway, I'm looking for a firmware that's stabile and support both HFS+ drives and have a DNLA/UPnP server function so I can share my HDD to both my PS3 and my computer(using XBMC). 

Been searching for some days now but can't find any fw that does both things.. :(

Any suggestions would be much appreciated!
