I've had my S3 since late last year and do not regret purchasing it. It's easy to use and very reliable. I would like to get a Slingbox so I can access my Tivo from anywhere in my home with my MacBook or on my PowerMac G5 in my office. I'm not sure which Slingbox to get. I thought the Pro was the obvious choice since it had the option to accept HD but apparantly it still downsizes to standard def. I can also go with the AV since the S3 can out put standard def and HD simultaneously through the s-video and component outputs. The AV is also cheaper than the Pro with the component cable. I looked at the s-video output of the S3 and it looks pretty decent and seems to handle aspect ratios correctly. Suggestions?
