Sure, it works fine but its implementation basically blocks it from use with commercially available DVDs. Anything with CGMS (on component) or Macrovision on S-Video or Composite is blocked from scaling so you are just deinterlacing a 480i source. I've found 2 DVDs that it will scale, AVIA and Video Essentials. For everything else, my progressive scan DVD player does just as well, since it uses a Faroudja deinterlacing chip. It did do a nice job of scaling these two mentioned DVDs, but I don't often watch them and I never watch them for enjoyment! I suppose one could use it (the Z9) to scale the output of a satellite or cable feed, but frankly, given the quality of the SDTV sources available via these it's not much of an improvement. Scaling a low quality image doesn't improve the picture quality I think that at this time, the scaling is a great marketing feature, but from a practical perspective it has substantial limitations.

1. The scaling feature is limited due to the standards of the DVD consortium not Yamaha. Any standard production DVD produced by the studios w/Macrovision are not compatible. However off-air video signals can be scaled, such as those coming from a Cable box, Sat tuner or Set-top box.. |
2. The Z9 uses global settings rather than independent, this makes it difficult for the user as setup parameters will vary by source input. For example, the Faroujda setup for a cable box would be significantly different than that of a VCR.. |

I care about the usable end result, I'm not going to get in the middle of a political fray between the content providers and the Consumer Electronics Association. Thank you for agreeing that the feature is essentially useless for DVD, and that it's the best quality source that's available. Scaling SDTV via OTA, cable box or sat feed is again, of poor quality, through no fault of the receiver. OTA Standard Def has tons of noise, which the scaler can't clean up, cable feeds vary -- an analog signal can look great or terrible, usually it's terrible. Sat feeds of SD material look terrible on a 55" screen, scaling it to 1080i will do a fine job of scaling the artifacts. Yes, I've used it with all of the above, and it doesn't take a video expert to see the flaws. I didn't even address usability, that's another topic entirely. I do have some substantive critiques in this area, that I'll save for the review. It isn't a bad product, but depicting the quite limited ability to scale as a great feature is a bit of hype that is, in my experience, unwarranted. Cheers, |
