If your interested in what i was worried about please read the A30 review, but it is rather long and apparently the mentioned performance in the
1080p mode cannot be fixed with
firmware updates but
it's ok with
1080i so no worries.
HD DVD performance
We started off our
HD DVD performance test with the
HD-A30 in
1080p mode and took a look at Silicon Optix's HQV test suite on
HD DVD. The first test we looked at was the video
resolution loss test, and the HD-A30 failed. It did not display the full resolution of the test pattern and the
image was unstable at many locations. As a point of reference, we run this same test on all HDTVs we test and almost every
HDTV passes this test without any problems. We also looked at the film resolution loss test and saw the same result--loss of resolution and an unstable image. The second part of the test pattern, consisting of a panning shot of Raymond James stadium, had some moire in the grandstands, although not as much as we were expecting given the test pattern failures.
The issue is clearly with the HD-A30's 1080p processing. When we flipped the HD-A30 into
1080i mode, the
JVC LT-47X788 had no problem properly deinterlacing the signal. Of course, that's the other side of the argument--if your
HDTV has good 1080i deinterlacing you can set the HD-A30 to 1080i mode and avoid the HD-A30's lackluster 1080p performance. But if you're going to leave the player in 1080i mode, you might as well save yourself a few bucks and get the
HD-A3.
We also looked at actual program material and, sure enough, the faulty 1080p processing reared its head. On Mission Impossible: III, we saw moire on Chapter 8 in the stairs in the background. It also popped up at the beginning of Chapter 11, where jaggies could easily be made out on the stripe of the limo as it approaches Tom Cruise. The HD-A30 performed better on Aeon Flux, but we could still spot evidence of faulty 1080p processing. For instance, in Chapter 9 at about 54:14, we could see jaggies on the grates in the background. When we flipped back to 1080i mode and let the TV handle the processing, the jaggies were gone. The effect wasn't present on every movie though. We watched the first half of The Bourne Identity and although we saw awful jaggies on the introductory menu options, the actual movie was relatively jaggy-free.
Interestingly, the HD-A30 performs much better when the output is set to 1080p at 24
frames per second output. We had the HD-A30 set to 1080p/24 connected to the
Sony KDL-46XBR4--one of the few HDTVs capable of accepting and properly displaying a 1080p/24 signal. We rewatched the stairs scene from Chapter 8 of Mission Impossible: III and the moire was gone; the limo from Chapter 11 was cleaned up as well. Unfortunately, few HDTVs can handle 1080p/24 correctly, which means most HDTV owners (even those with 1080p HDTVs) won't be able to take advantage of this excellent performance. However, for those that do own compatible HDTVs, it is one of the few cases where the HD-A30 may be worth the extra money over the HD-A3.
Load times for HD DVD movies were a bit of a disappointment compared to the
HD-A20. It took us one minute, 25 seconds to go from powered off to getting a picture on the screen for Mission Impossible: III, and the same movie loaded in 34 seconds with the player already on.
DVD performance
One of the disappointments with the
Toshiba HD-A20 was its performance on standard DVD in 1080p mode. It does not appear that the HD-A30 has made any major improvements, as we observed essentially the same lackluster performance on test patterns. We started off our tests with the
standard definition HQV test suite from Silicon Optix, over
HDMI in 1080p mode. It passed the initial resolution test, demonstrating it can display the full resolution of DVDs, although we saw more flickering than we'd like on several parts of the image. Next up were two "jaggies" test patterns and the HD-A30 performed poorly on both of them, exhibiting jagged edges where there should be smooth lines. This was also very evident in the next test with program material of a waving flag, with jaggies showing up on nearly every ripple. On the upside, it did successfully handle HQV's difficult 2:3 pull-down processing test, kicking into film mode in about a half a second.
However, like on the HD-A20, the HD-A30 performed better when we watched some actual program material. The introduction to Seabiscuit gives a lot of players problems, but the HD-A30 handled it very well, with almost none of the jaggies that often mar the picture. We also took a look at the opening sequence of Star Trek: Insurrection, and confirmed that the player does indeed have
2:3 pulldown processing, as it correctly rendered the curved edges of the bridge railing and hulls of the boats without a problem. So while the HD-A30 struggled with some of the more difficult video-based tests of the HQV test suite, it held its own on more common film-based program material.
