Hi, HDMI mirroring works on my Samsung TV at home. But on Christmas day I went to my Uncle's house and tried HDMI mirroring on their Insignia HDTV and it would not work this is with the Verizon OTA ROM. However many other people are reporting issues that it used to work but no longer does. Mine still worked after the Verizon OTA, but now I'm using Tweakstock v1 ROM. I tested it right now, here are my results:
Using Tweakstock and HDMI on my Samsung 2005 model TV:
Netflix works.
Samsung Media Hub does not work (I would love for a ROM to bypass this if possible!).
After the media hub I went to the Android Market to look for video apps, but when I had tilted my phone from landscape to portrait, the signal cut out and would not return. Odd, huh? What's worse is that my phone became unresponsive and the screen turned off and my phone proceeded to reboot itself on its own.
Needless to say I shan't be testing out the media hub again. :'(
