You might want to be more careful when you accuse others of misstating facts.
Denon has multiple 2007 models on the way. These include the $849 2308ci, $1199 2808ci, $1599 3808ci, $2499 4308ci, and $5199 5308ci. AVS has threads devoted to each of these models, save for the 2308ci. For your benefit, here is the link
to the 5308ci thread.
According to the product information sent to dealers, and reposted in the Denon 3808/4308 thread
, the 2308ci - 4308ci use the Genesis' Faroudja FLI2310, while the 5308ci uses Silicon Optix HQV processing, and more specifically, the Realta. According to posts by oyfoo of Silicon Optix
on this forum, there is essentially no difference in deinterlace and scaling performance between the ReonVX and Realta. The primary differences: the Realta
will scale to 2560x1600p, can handle less common cadences such as 6:4 and 8:7, and supports noise reduction on HD signals, whereas the ReonVX
is limited to 1920x1080p and only supports noise and block reduction on SD.

When properly implemented, FLI2030's SD deinterlace is better than the FLI812x in the 605-805. The FLI812x in the 605-805 has a built-in 8-bit converter to do the analog-to-digital (A/D) conversion for s-video, composite, and component sources, whereas the FLI2310 does not. The FLI2310 requires a separate analog-to-digital (A/D) converter.
As far as I can tell, the 3808/4308 and 875/905 are using the same Analog Devices' 216MHz NSV ICs to do analog-to-digital conversion for s-video, composite, and component sources. This is an upgrade over the integrated Faroudja 8-bit A/D conversion found in the FLI812x (used in the 605-805).

That comment makes absolutely no sense because Denon is not using the Faroudja to convert analog to digital in the 3808/4308. That's what Onkyo is doing in the 605-805. The approach taken for converting analog sources on the 875/905 and 3808/4308 -- using a dedicated A/D circuit from Analog Devices -- is much preferred.

I would not expect the Faroudja to offer comparable performance, but worse case, you can disable it and use pass-through mode. As always, I would wait for reviews, comparisons, and test results before spending $$$$ on a receiver.

This was evident with Silicon Optix's HQV test disc, as well as on Star Trek: Insurrection and Seabiscuit. Without 2:3 pull-down processing, we found film-based movies were filled with jaggies when the TX-SR605 was responsible for deinterlacing. For example, we ran our tests from the Samsung BD-P1000 to the TX-SR605 via S-Video, and then out to the Sony KDL-46S3000 using the HDMI connection. In this configuration, the opening sequence of Seabiscuit was filled with jaggies on almost every image that the camera panned on, with artifacts that would be noticeable to even those who aren't picky about video quality. Similarly, on the introduction to Star Trek: Insurrection, the boats on the riverside clearly had jaggies instead of being represented by a smooth line.
We also noticed that the TX-SR605 was softening the resolution of images that it deinterlaced; this was confirmed on the HQV test disc as well. In areas where there should have been detail, there was just a solid color. On the other hand, the TX-SR605 did a very good job with several other tests on the HQV test suite, including tests with a rotating white line, three pivoting fingers, and footage of a waving flag.
While the video performance of the TX-SR605 was disappointing, in our experience subpar video processing by AV receivers is common. We've mentioned it in reviews of the Sony STR-DA5200ES, the Yamaha RX-V1700, and the Pioneer VSX-82TXS.
