Thank you very much indeed! Your files are uploaded at our svn
repository.

Module name are (now) not prepared for translations.

This file only used by skin jason. But, i forgot to create a
translatable template. This template file is now (at svn repository)
present, see :
http://svn.berlios.de/svnroot/repos/xxv/XXV-Skins/trunk/jason/locale/lang-en.js

I think, the line  "POT-Creation-Date: 2009-08-15 00:07+0100\n" was be
missed.

See http://svn.berlios.de/svnroot/repos/xxv/XXV/trunk/locale/it.po


Kind regards,
Andreas

Here are parts of a discussion I had with a Nvidia developer 4 months ago:

I just tested VDPAU, and it looks like this is possible, to some degree.
Specifically, with 480i output over S-Video, I find that the presentation
queue flips at 60Hz, not 30Hz, so it's definitely only syncing to fields
not frames.

The hard part is that there's no way to specify if you're outputting a
top or bottom field, so it'll end up being random if your surface gets
displayed as top or bottom, which kinda makes the whole thing pointless.

We did acknowledge that this use-case might exist, but were of the
opinion that it was extremely rare; most users will simply de-interlace
their content and display it one their progressive display. Does your
display device not support any progressive modes?

I did some investigation, and it doesn't look like our HW exposes any status
indicating top v.s. bottom field, nor any way to request syncing of display
to top v.s. bottom field.

Sorry this isn't more useful! I will keep this request around as an RFE
(request for enhancement) just in case we can implement it on any future HW.

Oh, and it looks like we do support 50Hz output; see the README that comes
with the driver, and search for the TVStandard option.

Yes, out with an n Hz field rate, you should be able to derive either n Hz
frame rate or 2n Hz frame rate. The exact details are explained in the
vdpau.h documentation on video mixer usage, with some additional notes in the
driver README.

You can't do it with the composite output (using the nvidia supplied
breakout cables).

You can do it using normal dvi/vga output though, and use a
transcoder, or with a tv supporting rgbhv signalling, or just plain
vga/dvi/hdmi.

.. but you still have the problem of not being able to figure out the field
order? See the other mail I sent to this thread..
