I apologize if I've posted this in the wrong section... I have the option to purchase either a Sling Media Slingbox PRO-HD SB300-100 or a Sling Media SlingCatcher SC100-100 Universal Media Player for TV. Are there any major differences besides price? I noticed the "catcher" has an HDMI input... I'm new at this stuff and wanted to hook one of these up to my HR20-100 to watch television on my laptop and other televisions in my house... I also wanted to watch streaming videos in my house and be able to see my computer screen on my main television. Do either one of these option give me these requests? Thanks you in advance for any information that will help me to make a decision.
