I know this seems like a stupid question but hear me out. I just recently found out that it was possible to do streaming on a Blu-ray player, at least Sony and the Samsung ones. I was thinking that maybe it could be possible for me to install a IPTV player on the Blu-ray system so I have a Blu-ray and cable box. Thank you for reading!
I seriously, seriously doubt it. I don't know much about those players but unless you have access to some kind of built in app store that carries an IPTV app and allows you to install it or find a way to side load the app that is compatible with whatever Operating System your Blu-Ray player runs on, there is no way to get it working.
