Ok to help u guys i tried a 720p 6 gig rip. Freezes or stops in about 5 minutes on my TF and my Evo using upnplay and rockplayer. Standard def streams no prob on both devices using Rockplayer and mobo. Thinking it might be a wifi bandwith limittation i tried my archos 70 using its smb player and no probs. So its not wifi. Then i used the upnp built into the archos 70 and still no freezing. So the tversity media server is not the problem. So then i installed upnplay on my archos 70 played the video using the archos native player and still no problem so its not upnplay. Then i used upnplay with rockplayer on my archos 70 and it stopped within 5 minutes.so it would seem to be the players. Archos has alot of codecs and optimised as a media player since that is its roots. So at least u know standard def works with the setup of tversity, upnplay, and rockplayer or mobo but u need a different player like the archos native one to play high def. Long post but i hope it helps save u guys time.
