I''ve been poking at it but so far I haven't been able to figure out a way to make it work. I grabbed the deodexed dlna.apk from this thread: http://forum.xda-developers.com/showthread.php?t=824953
Not only did I fail at getting it to work for my Nook HD+, I even fail to get it working on my captivate, Honestly, I'm probably am no good at tinkering with code in the first place.
I'd be thrilled if someone could shed some light on this, my galaxy tab was stolen so now I'm sitting on a useless allshare cast unless I can get my nook or my captivate to work. Preferably the nook since my phone is due for a replacement soon since it's starting to show it's age on running apps at a decent speed.
