Well I figured it out.I don't think that your issue is with the TV, because you are getting the slideshow. I do have a TV that can't get anything from the Evo, and never could.
I would bet it is still in the kernel. You could do a nandroid backup, then start completely over. Wipe everything, then put on the rom you want to use, and flash the zip. But I wouldn't restore anything else. Don't use titanium or anything else, and then test from there. If it works, you know it's something in the install. If it doesn't, you may have a bigger problem.
The developer uses fresh, and I have it confirmed working on Ava, so you may want to try one of those.
I thought HDMI zip contained app which it doesn't so basically I wasted time flashing/re-flashing roms trying to get it to work lol
