[mythtv-users] MythArchive - wrong/slightly-out aspect ratio on DVD

   Revisiting mytharchive for the first tine in a while, I find that most of 
the issues I'd previously had & worked around have now been fixed, which is 

   However, I'm still stuck with a really odd one, in that my resultant DVD 
has a bizarre aspect ratio.  When I play back 16:9 recordings off the DVD, I 
lose bits of the left & the right of the picture:  it's somehow stretched.

   No ratio/display changes on the TV fix or work around it, and I've tried 
it on 3 players & 2 TVs, so I'm pretty certain it's something off in the disc.

   Oddly, though, playing it through, e.g,. xine, doesn't show the problem; 
  I guess it's more forgiving to whatever's 'wrong'.

   One thing I did look at this time which I hadn't before was the window 
that xine creates:  it's 768x480 [xdpyinfo] (which is a 1.6 ratio, as 
opposed to 16:9's 1.7777 or 4:3's 1.3333).  Which is even more odd, as 
unless I'm wrong that would make it *squashed* not stretched.

   I did a dummy create of 15s' worth and I can't find anything obviuosly 
wrong except:

WARN: attempt to update aspect ratio from 16:9 to 4:3; skipping

   [mythcenter theme;  guess I could try another]

   All other data seem OK:

   I find "720x576" throughout.

   I'm not sure where next to look.
