HD-A2 as an upscaling player?

[plissken99]

I can't figure this. The A2 and it's predacessor the A1 were great upscaling players... until I got the JVC RS1 1080p projector. Watching Star Trek Deep Space Nine, I've been seeing combing artifacts(the meteor in the opening credits is a prime example.

At first i thought maybe the JVC doesn't like the 1080i signal, so I tried it in the PS3 at 1080p, and it looks much better on the PS3. Then to test that, I tried it in the Oppo, no combing artifacts there. HD-DVDs look just fine, I can't think whey I would suddenly start seeing this with a new display device.

I plan to get the XA3, but until then, I guess the PS3 is my upscaling player

The arifacts you describe are not ones of scaling, but ones of deinterlacing. In both the PS3 and Oppo case, you are sending the RS1 an already-deinterlaced signal. In the HD-A2 case, it is still interlaced.

Therefore, it is likely the RS1 is not as good at deinterlacing as your previous projector was. If you fed your HD-A2's 1080i output into a Reon chipset for deinterlacing, such as the one in the Onkyo 875/905 & Integra DTC-9.8, it is likely it would be the best quality out of all your sources. I can tell you straight up that for SD sources the DTC-9.8's Reon is much better than my Sony HDTV and A35's builtin deinterlacers.

Actually I immediately noticed the A1's poor handling of interlaced video-sourced material right away compared to my Denon 2910.

This is one of the reasons I bought an SD upconverting player. I knew I would eventually have a HD-A2 and I knew it sucked at upconverting. Now I need to compare it to the PS3 I picked up and see if I can get rid of the SD-player.

Actually the Oppo is set to 1080i as well. Looking on the DVD Benchmark tests, I see the only video test the A1 failed was 'bad edit', which to them caused the combing artifact in The Big Lebowski DVD menu, that could account for what I'm seeing. Still it's weird I never saw this artifact on the Sony, or the CRT projector(and with the CRT it was the HD-DVD player purely doing the processing).

So yeah, until the XA3 which uses the Reon chipset comes along, I'll have to use the PS3 as the upscaler.

We don't know that.

It only stands to reason. And if it doesn't, I'd have to decide on Reon vs DTS-MA decoding.

[Sehnzeleid]

Well, who knows, it might go with the ABT2010, or the Realta, or a Gennum chip.

I can't really see Toshiba revisiting the Reon for their next flagship, that would be just lazy.

[plissken99]

Well this is hell. The A2 has the combing artifact, the PS3 has other undesirable scaling artifacts(solid colors have a visible pixel structure, red especially), and the Oppo just looks like crap(why I see scanlines like I'm watching a 1080i display, I have no idea). So despite the combing, the A2 is still the best player, and I have confirmed it only effects TV DVDs, movies look just fine.

If I weren't flat broke(thanks Xmas... and yeah RS1), I'd order the XA2 ASAP.

After buying one of the best PJ's out there, all this negativity?

I don't mean negativity towards the pj itself, but...wow. If I were you, the joy of owning the RS1 just got frustrating. And that sucks.

What's with the TV shows vs. movies thing and the combing? Are TV shows shot differently than movies? What gives with that?

Of course, I wish you nothing but luck and all and I ain't trying to rain on your RS1 parade but like I said....wow.

[plissken99]

TV shows are from a video source, so I'm guessing thats it. House looks fine actually, so far all thats effected is DS9 and The Shield. Anything else looks glorius on the RS1, if I weren't in the process of making my way through Star Trek there would be no complaints. I mean last night I watched friggin Haunted Honeymoon on DVD via the A2, and through all the grain there was an occasional 3-D moment! It is a great player, just don't handle whatever DS9 was encoded with well.

It's always true, the nicer the display, the nicer your sources need to be. This being the nicest display I've ever owned, I need top quality sources.
