Well, this weekend I played around with my JVC D-ILA projector and a Japanese JVC DH-30000, plus my DTC-100 w/169time option and a Panny D-VHS deck.
It was interesting to note that on the D-ILA forum, the JVC rep noted that the component video feeds shouldn't be used for HDTV on the D-ILA because of poor internal scaling and display artifacts.
The Panny was hooked up to the DTC-100 w/169time option (play only for now), and into the JVC D-ILA via RGBHV.
The JVC DH-30000 was hooked up both (via a splitter) to the component video inputs, and also via a Key Digital YPbPr to RGBHV transcoder.
This is a ISF custom calibrated JVC D-ILA, and all settings were the same for each input.
Very interesting results...
For starter, just using component video w/JVC D-VHS, the picture was overly soft, dark, and lacking in detail and color. Messing around (just for the hell of it) with the internal projector picture controls yielded little if any improvement. I then hooked up a Nintendo Gamecube and Microsoft X-Box via component (480p) just for additional reference. Both devices also suffered from an overly soft and dark picture, even after messign with picture controls.
When running through the transcoder (RGBHV) the picture did a complete u-turn. Picture was not only brighter, but had more detail, less noise, and more saturated colors. This goes for all three devices.
In running the same tape through the JVC D-VHS and the Panny/DTC combo, the DTC-100 w/169time option yielded a noticeably sharper picture. In fact, I'd almost say the picture was too sharp. It enhanced the picture noise and MPEG-2 artifacts, but not so much that it ruined the picture. Text and diagonal lines yielded aliasing artifacts. But the picture from 12feet back was just incredibly sharp and detailed.
The JVC D-VHS looked great as well, but displayed a slightly softer picture. Practically absent were the aliasing/interlace artifacts, and the colors from the JVC were more saturated than the DTC-100 combo.
I had another forum member over (he can speak up if he likes, otherwise I am not volunteering names) who witnessed this as well. He may have more comments to add.
But in the end, I preferred the picture of the DTC-100 combo. I'm one who likes to see the bleeding edge of sharpness, and again the DTC-100/169time combo looked great.
But I'm still keeping the JVC D-VHS unit only because of the discovery in this forum of region coding.
Anyway, I haven't hooked up the Panny DST box to the projector (the F connector is being repaired) but the Panny/DTC combo is a winner in my book.
I'll wait till a few more options are fixed before sending the play unit back to Richard for upgrading to record unit.
