Thanks for the suggestions and many of the threads on this topic offered several different ways people have gotten around this issue. It's just that I find it incredible that the companies that produce RV entertainment systems don't seem to keep up and that they essentially all push very low end systems. I guess for the very high end RVs, they simply install a small equipment rack and use high end home components. It just seems there is a market for the middle ground. Even car manufacturers are enabling the ability to connect to a wifi router to do firmware updates. But what is really funny is I saw a thread the other day about the King WiFi router that a person talked with customer service about firmware updates and the person said they don't do that. Now the router has an option in the menu to update the firmware, but sure enough if you look at their support site there are no firmware updates to be found.
I'm not sure it is true that Blu-Ray disk drives require firmware updates. Perhaps the software or firmware that then plays the disk does. I've had a USB Blu-Ray disk drive that I've attached to a laptop to copy movies onto a server for years without ever doing a firmware update. I might try plugging that into the USB port on the Jensen receiver and see if it will play a Blu-Ray disk. If it does, then it should be no issue for the manufacturers to put a Blu-Ray drive in their units.
Even if the firmware updates are required, more and more RVs are coming with routers that will attach to local WiFi. Also, more and more campgrounds are including WiFi so I'm guessing that's because more RVs come equipped with a WiFi router. So there is really no reason at this point that one of the RV entertainment system companies couldn't have a WiFi receiver that supports various streaming services and connects to the router in the RV.
I've also seen the comments that perhaps the companies don't see a demand. That is really one of the reasons I'm bringing this up is for people to bring up what they would like to see. Perhaps that is what I should do is start a thread that with a simple question ... What would people like to see in their integrated RV entertainment system? Maybe then take that input to create some polls about features. I'm new here so I'm still trying to feel my way around this site.
