I have a dilemma I'm trying to help solve...maybe one of you home theater buffs can help me find an inexpensive solution.

We have a PC with a DVI-D video connector in the sound/video booth. We want to connect it to a HDTV with an HDMI connector. The cable run is about 90 ft. Is there any way to do this inexpensively? The display will be used mostly for powerpoint, although sometimes for DVD, etc.

This looks like a great solution, but it's pretty pricey.
