The Pinnacle is the best kept secret in PC>TV connectivity. I only came across it when someone mentioned it in the SkyHD forum, so I made more investigations and ended up buying one. The performance of the box itself can't be faulted, but I feel the PC software could be a lot better. It's quite labourious the way that files are imported into the menus, and could be made a lot easier. It will also link up to a compatible Pinnacle analogue or digital TV card in the PC. The only other thing that lets it down is the lack of an HDMI connector, although it will go up to 1080i at 50 or 60 via the component outputs. I can't compare it to the Snazio, because I've never seen one.
We use our SC200 almost every day, either watching HiDef downloads (e.g. 24 in HiDef) or all our DVDs that I've ripped to XViD. Works flawlessly over wireless (802.11g). Ours is connected to a Samsung SP46L6HX HD-Ready TV using component. The lack of HDMI output didn't bother me since our TV only has one HDMI socket and that's reservered for Sky+HD when it arrives.
The only possible downside to the SC200 is that Pinnacle have gone very quiet on the support forums since they were taken over by Avid, so long-term support may be limited.
Agree with the previous posters- have had a showcenter 200 for a month now and performance is great-yes the software leaves a lot to be desired but it's still IMO the best option for getting your PC content flawlessly to your TV
Ive got the 1310 and it plays HD perfectly over my wired Lan and also from my 400GB packard Bell USB harddrive thats formated to NTFS, its a shame wireless cant quite keep up with HD stuff, its very close but to many pauses realy.
Like I said though over Lan and via USB hard drive its perfect.
