Adding a hdmi cable to rear TV

A quality HDMI cable can easily run 75ft
Wireless is a solution ... However I have found it to be problematic at times with Interference and Reliability issues - additionally you will need to power both transmitter and receiver
A simple 1x2 HDMI DA aka splitter (it will require power, many times 12Vdc) can be found on Amazon / Ebay for less then $10.00 - A quality 50ft HDMI cable for less than $20.00. IMO a hardwired installation is far superior to a wireless connection.

Though some are expensive, there is also HDMI wireless devices.

Thanks Roy, I knew someone had mentioned something about this.

As far as a second player in the back, what happens when someone in the back wants to watch the same show that is playing in the front. Maybe with the couch and dinette there would be enough room for the four of us in the SW but not in our Bounder.

HDMI cables of very high quality are good for at least 50 feet and with an amplifier much further. In the Bounder the cable is 35'. A powered splitter however is a necessity when you have one input and two outputs. The splitter I bought has the pass through feature, maybe all of them do but I only use the splitter when playing a video disc.

The cost of the cable and the splitter were less that a decent BluRay player would be. Installation was a bear in the Bounder but should be much easier if RoyB is correct.

The easiest path we found for getting from the front area to rear area of the trailers was to run down the ceiling air conditioner foam ducts.

Easy access on both ends as there is usually a ceiling mounted cabinet near-by.

I just dropped all of the air conditioner vents along the way and fished my wiring from vent to vent. These are usually just six feet apart going down the center of the trailer.

Just be sure to patch where you entered the foam ducts with expanding foam sealant to prevent the engineered air conditioner air pressure to remain the same.

I have VIDEO and RG cables for my Ham Radio running through my air conditioner foam ducts...

X2 on a second BluRay player, way easier and better. Even if you could run an HDMI cable the signal would probably be poor at that length.

While I apologize that I do not have an answer to your question, wouldn't it be cheaper and easier to install a 2nd BluRay player in the bedroom?
