This is probably the best place to ask questions. Here are my initial thoughts:
1. The PC in Seatlle is irrelevant. That will only be used for the initial setup and a 20-yr old PC running Win95 would do
2. Any Slingbox will do what you want. If I was in your position I would probably go for a used Solo off E-bay, But if you wanrt to watch HD (and have an upload speed in Seattle of at least 5Mb) and your DVR has only an HDMI output you will need a 500.
3. Watching on a TV at PA is difficult as the Sling system is really designed for watching on a PC or Mobile device. if you want to watch on a TV you will need an additional third-party box suxch as Roku or WDTV or AppleTV.
Feel free to follow these up
Thanks Alan. You / this is great. I would like to watch the recordings in HD, so I have to ask "500" what? The HD DVR in Seattle is connected wireless, or so I'm told. I will check on the upload speed. It was my intention to purchase a new P/C with a large monitor for use in PA, so perhaps I'll be able to watch those games in something close to HD, and forget about watching on my TV in PA.. The new P/C would be hard wired into the router and it also has wireless capabilities. Sould I be concerned about my download speed in PA? Sorry about all the questions.
You can probably tell that I've recently crawled out of a cave and into the 21 century. Thanks. Richard
The 2 current Slingbox models are the 350 and the 500 and the 500 is the one with HDMI support. They are replacements for the Solo and the Pro-HD, both of which are still very capable boxes.
DVR connection method irrelevant
And download speed in PA is not really important unless you are on dialup It is the upload speed at the Slingbox location which is normally the bottle neck.
