I've never used a DVI port on an HDTV, but I've read reports that say that some DVI input ports on HDTV are not compatible with computer DVI output. There are many different types of DVI (too many), so this might be a problem depending upon which type of DVI output port your Mac has, and which type of DVI input port your HDTV has. If you plan upon using DVI, I'd check to be absolutely sure the two ports are compatible. Similarly, there are many types of DVI cables, so if your setup doesn't work, it could be you have the wrong type of DVI cable.
HDTV VGA input works with computer VGA output, BUT, it's important to remember that the resolution/refresh rate combinations that are acceptable on HDTV are normally VERY limited over any type port. An HDTV isn't a multi-sync monitor, it has only a few setting that don't stretch or compress the image. There needs to be a match between the required "native resolution/refresh rate" of your HDTV and the output available from your Mac.
One thing I learned when hooking my G4 Mini to my HDTV was the strange fact that Tiger & Leopard have different sets of output resolution/ refresh rate pairings for the same video card, in my case a Radeon 9200 mobility of the G4 Mini. If you can't find the exact correct combination to work with your HDTV, you can try the alternative OS version to see if it has what you need.
A third option is to use something like SwitchResX to create a custom setting to match your HDTV input, but I don't believe this is a good option.
