(If you are looking for explanations of each item, I'm not the person. Somewhere in all of these pages just about every setting has been covered.)
Somewhere in 340 pages is easier said than done, especially with a generic term like "crop" or "aspect ratio".
[QUTOE]To answer your DVD question - you want to set the Crop to 4:3 and the Scale out to Anamorphic. If your DVD is anamorphic, then it will be properly expanded to a 16:9 ratio. If it is 4:3/non-anamorphic, then it will be displayed that way.[/quote]
Those can't both be right. I'm lost. My understanding of Anamorphic out is that whatever's left after the crop is stretched to file the output area. So with Crop 4:3 and Scale out Anamorphic result in everything being stretched to fill the screen?
My real question is what happens if you pick Crop 4:3 (or 16:9) and set Output to Letter/Pillarbox?
I still can't tell if crop actually crops or if it just changes the interpretation of the input.
Strictly speaking, there is no such thing as a 16:9 DVD - it only becomes 16:9 after decoding IF it was encoded as anamorphic.
Strictly speaking DVDs have a Pixel Aspect Ratio of 1.5:1 but that represents either 4:3 or 16:9 image.
For HDTV, which actually DOES arrive in a 16:9 package, you want to set it thus - Crop to HDMI Autodetect and No Scaling.
Wouldn't no scaling mean that only content with the same resolution as my display would fit? In my case wouldn't 1080i content run past the edges of my 720p display?
I don't have a BD or HD-DVD, but I would imagine it would be the same as HDTV.
Custom Crop is primarily for specific problematic display devices. I would think you wouldn't need it.
Actually I will.
As far as 4:3 in a 16:9 frame, I have no idea what you're referring to.
For example upconverted SD channels, which are pillarboxed.
If you mean a DVD of (for example) a 30s/40s movie - that's merely a 4:3 aspect ratio movie. Crop = 4:3 and Scale = Anamorphic.
Firstly, 4:3 on a DVD isn't what I'm talking about, second, wouldn't that stretch the 4:3 image to fill the screen?
The D2 will take care of detection and proper display. Throw in a recent 16:9 release and the D2 has your back. No problems.
How, that's my biggest problem, half this thread seems to be handwaving "it works".
You could do worse than searching for all Bob Pariseau's posts in this thread and reading through any longer than 10 lines. He's really good at explaining the fundamental concepts we all need to know to use this product. Maybe that's why you haven't got answers - possibly everyone thinks Bob would explain it better anyway, so why bother?
I've read through a number of his post, in their entirety, but all of the ones I've read are dealing with very specific questions that don't answer any of my questions. I still haven't found (for example) if the Crop input 4:3 and 16:9 modes actually crop the image or if they just change the scaling.
