So I tested a Zotac Intel Atom based nettop with my sling adapter running 5-8mb/s in HD. It works well. All 4 cores run at 85-90% so I'm thinking this hardware in this config can just barely handle it.
This particular nettop has 2 gig memory, atom 1.66, nvidia ion integrated gpu.
Cool been looking at a Atom 525 system myself (Dual Core 1.8) to put at the bedroom TV. Video and Audio are both good on your system?
So far my Sling Adapter seems to be working fine as far as watching TV goes. I'm able to stream to PCs within the house over our wired network and the video looks pretty damn good. I'm able to watch on my Droid X both on my home wifi and over Verizon's 3g network, and that also seems to work pretty well. Like others have reported already I'm not able to watch recorded shows on my phone...only live TV.
I do have one annoying issue though. After disconnecting from my remote session the DVR resets back into single mode, but all I get on my TV screen is a grey screen. I can still hear audio, and the weirdest thing is that I can still see any graphics displayed by the DVR, such as show information and the guide. I just can't see the actual program.
Is anyone else seeing anything like that? I've actually had to reboot the DVR twice just to get video back.
I haven't been able to do any tests but I am going to put switching the DVR to Dual mode when I think I might use the Sling. Seems that its control of Single->Dual->Single is buggy and it messes up my recordings. Since I am the main user of the TV, switching to Dual won't really affect anyone else in the house (my wife).
