I have the Slingbox 500 with 2 devices connected to it: TiVo (HDMI) and Dish Hopper (Component). Yes, remotely, I can select which DVR I wish to Sling. Further, there are power buttons for the devices on the Sling remote, so I do not need to leave the DVR's "on" but I can put them in Stand by and take them out of stand by (turn them on) all remotely. I'll try to relay based upon my personal experience.
The TiVo via HDMI on the SB500 passes through the SB500 device to my AV Receiver with no issues. TiVo is OTA only so I use HDMI because there are no content flags preventing recording no re-transmission of the content. For the Dish Hopper, I must use component because HBO and, I think, Showtime, have protection preventing recording and re-transmission, so the components guarantees that all content can be "Slinged."
The easiest way to watch your Slinged content is to purchase a "connected device" such as the WD Live. These "connected devices" come with the Sling app already pre-loaded at NO additional charge and these devices can be connected DIRECTLY to your HDTV via HDMI, etc. Go to the Sling website for the complete list of connected devices and please note the ones no longer in production such as Boxee Box. This functions as the old Sling Catcher.
If you sling your content to something on the same network within your home, it uses you home network ONLY to Sling the content and never Slings via the internet, so this provides for excellent quality and minimal lag.
However, if you wish to Sling to a remote location, then it does need to send it via internet. Aprox. 7Mbs provides the most excellent experience for HD content. However, Slings proprietary encoding can achieve very good results with HD between 5-7Mbps. You will have to experiment with PQ settings (Best, Good, etc.) to see not only how good it looks, but how RELIABLY is streams without stuttering or having to re optimize, but the Sling box can AUTOMATICALLY optimize by examining your internet connections. Manual selection of PQ is something to experiment with by pushing the boundaries of the internet traffic. Again, Sling's proprietary encoding achieves the best results among all such remote streaming devices with the least bandwidth. It's not going to look better (likely worse) on any other streaming device on the market today. I believe Sling officially states that the upsteram must be at least 7Mbps for reliable high quality HD content. Your stated speeds at both ends don't present a problem, but how the stream travels and the distance traveled through the internet could rear its ugly head at your remote location, and how your ISP at either location deems such consistent use of such high bandwidth at either end should they decide to throttle at either end. I can't see if you mentioned if you had a data cap, but if so, that may be a problem
The PQ via Component is really quite good and it seems a kind of MIRACLE one can stream so from far away with good PQ and not have to pay the high priced alternatives such as a second pay TV account, but there are some compromises: since it must stream via internet and for such a long distance, there will be lag from your command at the remote site being sent to the box miles away. So, if you press the guide button, it can take several seconds for the guide to pop-up, and this lag is the case for all other commands. This is NOT the instant speeds you are used to when the box is a few feet away from the remote control at home. That lag seems to be the biggest compliant form people. If you can live with the lag, considering the money you are saving, then it will work VERY well for you since you seem to have internet connections that are ideal for Sling.
You must try this out for yourself. You may want to purchase the equipment at Costco or Amazon or any retailer that has good return policies should you decide the lag is something you can not live with. Again, it is going to be the lag with commands that will be the only real compromise and if you think it is worth it. In many cases people Sling just to watch a show or two on the DVR live or recorded: they are not channel surfing. If you are going to do a lot of channel surfing, guide browsing, etc., it can be a TEDIOUS experience, but once you settle down for a show, it is great.
Best of luck.
