HDMI to DVI: Computer on TV

First of all if this is posted in the wrong forum or already been answered, please forgive me. I could not find any answer to this issue.

Ok, so in December I bought a 40" Dynex Flat screen LCD TV with 3 HDMI ports. I started thinking about how much I like watching the AVIs I have on my Mac (Dual 1.8 ghz PowerPC G4 with 2 GB SDRAM) so I started looking online for a possible HDMI to DVI connection cable. Well, I found one and ordered it (http://www.amazon.com/gp/product/B000HDL09U/ref=oss_product).
The cable came to me a week ago and when I connected it to the TV everything was fine. I was nice seeing my computer display on such a HUGE screen (I would have to go into system preferences and change the display to 1920x1080 whenever I plugged in the G4 to my TV).
Everything was fine until last night. I use this program called Cellulo to watch the AVIs and while I was watching an episode of True Blood, the picture froze. I tried pressing ESC, everything! Nothing would work so I had to press restart on my computer. The computer started up fine on my TV with the gray apple and the 'start up/loading' wheel showing it was loading properly, then, the TV went to a blue screen and said "no signal". So I switched back to my other LDC monitor and the computer display was fine. But now whenever I switch cables and try to plug my TV into my G4, it just says no signal and is a blue screen like nothing is connected at all.
Any ideas on what happened and a possible fix?

Monitors often accept a much wider array of resolutions and refresh rates than TVs. Did you verify that the computer was still set to output 1920x1080 at 60 Hz?

Unfortunately 1920x1080 is only available in system preferences when I have it connected to the TV and NOT with my monitor. My monitor only goes up to 1640 or something like that.
