Don't know if your response was sarcasm or not but those were the two least helpful answers that I have seen all week.
Back to your question....
I've used the mini with several Samsung HDTVs but not the model you mention.
Regarding using as a media hub, check out plex, boxee, or frontrow. Look in the AppleTV section.
As far as connecting the Mac mini, I have had various results. I use the Apple mini-DVI to DVI adaptor connected to a DVI to HDMI cable. Concerning media center use, it worked fine on all the Samsungs that I have used.
When using the MacOS and the TV as a monitor, an older model Samsung could not scale pixel by pixel but many of the newer models can. Check out AVSforums dot com for many details about using HDTVs for computers.
The two key terms to look for are overscanning which means you lose part of the menu bar on top and part of the dock on the bottom.
What you want, if using as a monitor is pixel by pixel mapping or some tech phrase similar which means that everything fits the HDTV like a normal computer monitor. NOT overscanning.
For a media center, overscanning is usually not a big concern since it is usually only between 3-5% and you won't miss that when watching your movies.
