Xbox 360 HD DVD Back
I need to reiterate that this HD DVD player is not a standalone unit like the Toshiba HD-A1. From what I can tell, basically all the Microsoft player does is spin the disc and send the data to the Xbox 360 for video processing.
So the basic initial setup was to attach the player to the console with the USB cable and connect the Xbox 360 with Component HD AV cable to the Olevia 747i 47" 1080p LCD that we're reviewing.
We used Peter Jackson's King Kong HD DVD, (included in the box with the player), to test if this player was a beast or a bust.
With one of the recent Xbox 360 updates, you can now go to the System menu and select 1080p as the output resolution. When we played the game, Gears of War (notable for its high def 3D artistry) in the Xbox 360 console's DVD player - not the separate HD DVD player - the Olevia indicated that indeed the source was 1080p 60 Hz.
But, without changing any settings, if we switched to playing the King Kong HD DVD, the TV screen would flash momentarily and then begin showing the movie. Now, when we queried the Olevia, it indicated that the source was 1080i 30 Hz.
Go figure. And that is exactly what I did, with four calls and three emails to Xbox customer service and an expedition onto the forums. I'll spare you the details about my harrowing exploits that I have dubbed, "In Search of 1080p, My Safari on Numbskull Island.")
To cut to the chase, I discovered that the key to pumping 1080p through the Xbox 360 system was using their VGA HD AV cable, (sold separately wherever Xboxes are found). So I dutifully went out and purchased the VGA cable and replaced the Component cable. (Here's a cost saving tip. Thankfully, non-Microsoft cables are available for about half the $39.95 price for the Microsoft branded one.)
VGA HD AV Cable
Remember, there is no reason to run these 1080p hurdles unless you have a 1080p TV and beyond that, your TV must have a VGA connector. Even though our Olevia meets those specifications, initially, it would not play back the 1080p Xbox signal with any acceptable quality.
After a lot of gnashing of teeth and accepting that it just wouldn't work, I began writing this review; and then, lo and behold, Microsoft updates the Xbox system. And the VGA signal plays back on the Olevia like a champ.
I must warn you however; I will not vouch that this VGA solution will work on every 1080p TV. In fact, the 1080p JVC LT-40FN97 review unit here still refuses to play back the VGA signal, though it performs vibrantly with the 1080i source through the Component cable.
