It seems that you are having some issues with your Slingbox since it gets so hot and might not work in a proper way.
This issue could be related to a faulty power supply. If your Slingbox is under hardware warranty (1 year), we recommend that you contact us so we can fix this for you as soon as possible.
Be very careful here. I came home yesterday to find my slingbox smoking and the living room stinking like burnt electronics. I bought it in June so BestBuy will credit me back...however...
"We don't have any in stock now. Sling is coming out with a replacement model so we can't get the current one you have/had"
I'm not sure I'd want to replace it even if they did have one. It was running a bit warm since the start but it never got hot enough to cook on..until yesterday.
Sling? Any word on the validity of "they are discontinuing due to 'issues'" comment the retailer gave me?
