How do you enable it so you know everything is set right?), set the DVI input type to 422 component (is this what they're referring too?).
After all this is answered, I would also like to know if this is the correct color space setting to use when using the DVI input of the Sony Ruby as well as the HDMI input?
Thank you, thank you, thank you, for any and all clarifications. :)
I have the Lumagen HDQ and the Toshiba HD-A1.
I agree that it is a little convoluted, and the FAQ might be worded a little differently, but it is easy and makes sense (after the fact).
Here is what you need to do to get the correct colorspace out of the Toshiba HDDVD players: (assumes latest firmware is loaded on Lumagen)
You make two changes to the Lumagen settings â€“ no changes are needed to the Toshiba.
For the input that the Toshiba is connected to, on the Lumagen:
1) set the EDID option to â€œUSERâ€ â€“ when you do that, you then get a list of capabilities that can be advertised â€“ make sure that 422 is enabled in that list.
2) Change the DVI/HDMI input type to 422
Power off the HDDVD â€“ power it back on. You have to do this step for this to work.
You are done. Donâ€™t be alarmed if you see the Toshiba menus turn green â€“ I see this, but when you play a disk â€“ it looks correct. I think the green menu thing is a Toshiba HDMI bug.
As to the difference between 4:4:4 and 4:2:2 â€“ my understanding is that the data is stored on the disk as 4:2:0, and comes out of the decoder(s) as 4:2:2 for both SD-DVD and HD-DVD regardless of the codec being used (someone please correct me if I am wrong). As to any difference between 4:2:2 and 4:4:4 â€“ I donâ€™t know if it is a lossless transformation from 4:2:2 to 4:4:4 (just padding with zeros?), but is seems prudent to me to use 4:2:2 to avoid any potential format conversion issues.
