A) What is "nvidiawhatever.run"?

B) what does "modprobe" mean?

If you click on the link in the 3. post upper, you will see how to download the driver directly from nvidia.

A) nvidiawhatever is the exact file name, including the version number, you also can see the exact command in the link.

b) modprobe is a command (application)

Using nvidia 180.29 on ubuntu 8.10
Should I compile ffmpeg separately?

Not sure why it doesn give me VC-1 decoding as the card is supposed to support this.

As always, thumbs up for this great project!

Compiled r17752 yesterday due to broken code in the later commits and successfully played some 720p content. The CPU (E8400) was at 2-3% per core all the way, also at higher bitrates (15-20 Mbit/s).

However, when playing 1080p content, I saw no image but a garbled desktop from underneath XBMC. OSD popups display fine, audio plays fine but no video. I connect my htpc to my flat TV via HDMI only (video+audio), latest NVIDIA driver (180.29) and the screen resolution is set to 1080i@50Hz, which is the only resolution which my TV can display natively (1:1 pixel mapping).

The standard SVN builds of XBMC (no VDPAU) work just fine for all content. Anyone experiencing the same?

I am experiencing very similar issues with 1080p on r17786 as the following:

With auto refresh rate enabled: exactly the same experience with all x264 mkv

With auto refresh disabled: Some x264 mkv is working, but some is not (including killa sample), in this case I have the same experience again (collapsed/ garbled picture, while audio and OSD is OK)

j0bro · 2009-02-17 12:15

Interesting, that means that either 1080p mkv files have different properties that are not handled well by the current implementation VDPAU, or the higher amount of data is the culprit.

@motd2k: Could there be something like a buffer overflow while doing the off-screen rendering in the backbuffer when playing 1080p content?

@Olympia: What are your desktop resolution settings (especially regarding interlacing and refresh rate)?

So, what are folks doing to get the latest NVIDIA drivers onboard smoothly? From the looks of the TRAC these changes are moving into mainstream code and I'd love to play with them on my machine!

Easiest IMO is to get the .deb packages from jaunty and install them in intrepid. They just work fine. Get all packages with 180 in them.

How much video ram do you green guys have?

It seems, that we use the same mobo (j0bro and I).
For me everything is default regarding video settings in the BIOS.

So you say we have to play with the video ram size?
I will check this out when I arrive home (If it is the problem, I hope it is possible to increase RAM allocated to video).

Refresh rate changing still needs to be fixed, vdpau context needs to be recreated after refresh rate change.

Your default video ram is likely 128mb. You should increase it to 512mb.
