Oh yeah... model number. Kinda missed that. [smacks forehead]
It's an HLN56W w/ 2nd gen DLP.
Incidentally, I just did a google search for that model number to do a visual check and google returned a long dead thread on this very forum where I once answered a post about that particular TV. In that thread I provided a link to an online manual and slap me and call me Susan if the manual doesn't say the DVI connection is HDCP compliant. It does! That's gotta be some kinda weird fate where I provide myself an answer in 2003 to a question I ask in 2008.
Long dead thread.
Link to manual
So I guess I'm safe. Woot! Right?
