Just pumped some SNSD tube mv into pi. (took like 1++ hr via ethernet, psftp, put command, about 3.35gb worth, which didnt like names that got special korean/chinese char...had to clean up the names.) Anyhow, some are 720p, SD and some newer ones are 1080p. Plays perfectly no lag, sounds comes out nice. My setup is just 3.1, but the subwoofer is a technic speaker, that after 20years still works... if you are a sound/speaker guy, you probably know, the surround foam on the thing is flawless, unlike certain karaoke brand speaker that my Mom was using, the foam disintegrated after like 5yr.
I never realise what a gem the old 3.1 speaker offers. Watching things like One Piece, Naruto, Fairy Tail on it, damn the bass is powerful.
All the while playing, the transmission is faithfully dling at 50KB/s. (I know slow, but I dont have unifi, and having the Pi allows me to download and upload constantly.)
My CEC remote, the fast forward works, rewind somehows works like its fast forward too...
I cant figure out how to right click.
For general, play, pause, stop, navigate playlist, skip forward or skip chapter, its ok

Good to hear Samsung TV working ok. I wonder if it is a driver/software support thing. If it is, hopefully it will work better as the support from open source guys increase.
For now, I think I got more then I expected. Works better then the shitty netbook that cost 7 times more then the Pi.
(I will need to find a way to set up network share, or a low power harddisk via ethernet/usb.) I fill up the 32gb way too quickly.
Less then 14hr and i have 15gb left out of the 32gb. If I transfer copy of 720p movie... bam finish
I wonder if something is taking up all those memory...
edit: Apparently, after testing out the "picture" function on the raspbmc, seems like it constantly hang up the program. Causing it to restart. Fortunately, I think the transmission daemon isnt affected. so torrent continues in the background.
