I'm asking because I sent this patch last year (or at least I wrote it and we discussed it on IRC, since I can't find an email archive link to it), and back at the time the picture aspect ratio was the big question mark. My recollection is that CEA-861-F introduces these new picture aspect ratios in the mode tables but never specifies their values. As a matter of fact, the AVI infoframe where these values are used only has space for 4 values (none, 4:3, 16:9 and reserved). Would you mind pointing me at the specification for these values?
