Aspect Ratio

Based on your description of the Aspect Ratio API, I sort of got stuck in the 
Ogle Source Code.... Here is what I have:

I have four modes in Goggles:  Autodetect (DVD), Autodetect (MPEG), Force 16x9 
and Force 4x3.

  switch(mode){
    case 0: DVDSetAspectModeSrc((DVDNav_t*)navigator,AspectModeSrcVM); break;
    case 1: DVDSetAspectModeSrc((DVDNav_t*)navigator,AspectModeSrcMPEG);break;
    case 2: 
            DVDSetAspectModeSrc((DVDNav_t*)navigator,AspectModeSrcUser);
            DVDSetSrcAspect((DVDNav_t*)navigator,AspectModeSrcUser,16,9);
            break;         
    case 3: 
            DVDSetAspectModeSrc((DVDNav_t*)navigator,AspectModeSrcUser);
            DVDSetSrcAspect((DVDNav_t*)navigator,AspectModeSrcUser,4,3);
            break;         
    default:DVDSetAspectModeSrc((DVDNav_t*)navigator,AspectModeSrcVM); 
            break;
    }


Here is the experience while playing a DVD:

1. AspectModeSrcUser is actually never checked for. User and MPEG seem to do 
the same thing.
2. When you set the aspect mode to VM or MPEG the ratio values are never 
updated (the last setting set by DVDSetSrcAspect is used.  So we need some 
way to redetect those values. Not sure how, since the nav is actually sending 
those values...
3. Trying to set it to USER has no effect. Unless you set it back to VM, then 
the aspect values you've set with user are taken.
4. Which one do I have to call first if want to set the aspect to user?  the 
set aspect mode and then the set src aspect? or the other way round? If I set 
first the mode to user, it will use the wrong aspect values since these are 
provided later.
5. The Goggles implementation of the User Interface for this seems to be done, 
but it still needs some work in ogle
6. Not sure about this, but the "send_demux_sectors" in nav.c doesn't check if 
the aspectmode is in USER... so it will override the aspect ratio no matter 
what the GUI had set it.

Hope this helps,
