There were a discussion over at MacRumors http://forums.macrumors.com/archive/index.php/t-745430.html where I posted the following:
So I bought my 37B658 LCD with all the whistles and bells also... that might have been a mistake thinking that I could skip the AppleTV box I have sitting next to the TV.
First off all there is a latest version avail from Samsung of their PC Share Manager - Ver 2.1 is out - if you can get it to work on a PC.
On my Mac Mini 1.66 GHz Intel Core Duo running 10.5.7, I tried Rivet (2.2) and EyeConnect (1.6) in different setups - wired and wireless - yes I bought the wireless dongle also... I also tried installing the Share Manager under Virtual Box but never got any connection with the TV.
Wireless DNLA - do not go down that way. You might be lucky and get it working, I didn't. Tried two different WLAN setups (subnets) and could not get a reliable linking. So save yourself the wireless dongle and go wired.
Rivet gives errors with "unsupported file format" when trying to play/show, but album art and picture preview works ok.
EyeConnect on wire works ok. On wireless I get errors with "unsupported file format".
So what can it be used for? Sorry but it cannot replace the functionality with regards to the ATV. Can only play chunks of music that one selects, it is just so simple file oriented! That might be ok for sporadic showing of a family picture or 10, but not a whole show! After this exercise I just love my ATV.
Internet - Yahoo widgets. Yes they work wireless, except for the You Tube one. I does not show anything in any of the menu selections, the only one working is Seach, which is not so fun. Again my ATV does the job much better.
