Which digital media player plays full ripped DVD's ?

I've setup a test system on my old laptop running XBMC and Windows file sharing while I consider ripping my DVD library and ordering a ReadyNAS Ultra. I've been able to stream full DVD's (one folder with many *.VOB files) in my house over 802.11g to a 1st gen AppleTV running XBMC. The quality is great, and it takes about 7 Mbps of bandwidth. It is slightly cumbersome to navigate to the DVD since I haven't yet gotten the XBMC library to recognize my test DVD's. There is a slight lag (a few seconds) when starting the DVD, but it is much faster than my slow DVD player. Fast forwarding, rewinding, and skipping chapters seems fine.

I also setup Air Video on my wife's new MacBook (the old Windows laptop isn't fast enough) and have streamed .VOB files to my iPhone over WLAN and 3G. The quality at 384 Kbps is quite good. The free iPhone app only shows some files, so I can't evaluate the full DVD functionality. I'm concerned it may not support the menu navigation and special features.

Can I assume from the replies in this thread that DLNA TV's, DVD players, and other simple players may not handle full DVD navigation?

I would like to also get my Wii playing full DVD's and probably buy an XBox too.
