OK. I got it. And let me just say that there is no way I know enough about or am passionate enough about this stuff to give anywhere near as in depth or detailed a review as others do in this forum (so please be gentle with the flames). It's bedtime, so I'm not going to be as detailed as I could be. I'm drunk and tired and haven't given this thing much time yet. So here's the dump of what I'm seeing so far.
First, I bought this from techonweb.com. I ordered it Friday since their web page said it was in stock. As soon as I checked my order status online that day it showed "shipped" as the status. I finanlly got an e-mail with a time stamp of 8:01 this morning (Tuesday) with a tracking number. I ordered it ground, and it was picked up in NJ at 11:21 Monday and left at my house (near Annapolis, MD) at 9:45 today. This in spite of the fact that it was supposedly shipped "FEDEX GROUND SIG REQ" and there was no one home. I opened the huge box with no packing materials, and found my new LinkTheater ratteling around in there. The LinkTheater packaging itself seems fine. Yeah!
Hooked it up to my Toshiba 56" HD RPTV (component and coax digital audio)and ran setup. No real problems there. I installed the software on the Windows PC (I use XP Pro)and it doesn't look like it installs as a service (no real investigation yet). Later added the UPNP device to Windows Media connect and it seems to work just fine (shows two devices for the same server on the buffalo, one entitled WMC), but I haven't really tested anything but WMVHD on the WMC side (which has the same problem described below)
It mostly works. I can stream just about every file type I've got (DIVX, RM, WMV, AVI, MPG, ISO rips of DVDs, WMVHD, and DIVXHD).
The WMVHD I downloaded from MS website plays beautifully but no sound. The WMVHD that Atom Films downloads to my PC doesn't play at all (weird pixelated, unrecognizable video, no sound).
Everything else plays quite well so far. FF / RW is choppy (not unexpected), and rate seems dependent on the encode rate (but only very preliminary testing so far). Zoom works fine here.
It seems to lock up occasionally when I'm using FF/RW (and other remote commands - i.e, >>| on previews at the beginning of a DVD). Sometimes I have to keep hitting FF before it will go back to play. Actually, lots of remote unresponsiveness / bizarreness.
DVD playback is not quite what I'd hoped for. Zoom doesn't seem to be supported (only tried one DVD), and FF/RW is pretty choppy, but sound and video during playback seem good.
I'll give more details later, but my first impression is: "Not ready for Best Buy, but beats the hell out of Roku because it at least plays my video files."
Next: Music, playlists, etc.
