Hi,
I have an onboard nvidia 8200 graphics card, using vdr-1.7.15 connecting with xine and using xv , not vdpau At the moment out of habit I am using the nvidia proprietary driver, but should I use the open source instead? Which one is likely to yield better performance in my setup?
Cheers, Art

Still the nvidia proprietary driver. There as been various benchmark of nouveau vs nvidia at phoronix which clearly shows there is still a long road for nouveau even if it is making steady improvements and old chipsets are now nearly on par. It vastly depend on the CPU you have to help GPU.

I also know guys who tried Nouveau but switched back to Nvidia because of the immaturity of the Nouveau driver. Another big negative for Nouveau is that there are no plans to support VDPAU. That drivers seems like a case of too little too late.

I've just tried to use a tnt2 card with the nvidia legacy drivers because a couple of capacitors blew up on my newer card. It didn't work, undefined symbol. Same thing with ati cards. For example my work computer had an ati card and fglrx support for it went away before warranty of the computer expired.
Open source drivers are needed so that old cards can be put to use even after the manufacturer doesn't care to support them anymore.

There's nothing wrong with what Nouveau is attempting to do. It's a good thing for people who still care enough to use old EOL cards. You can always argue why throwing some old outdated hardware out if it still suits your needs vs. replacing with something newer and _cheap_ while easing the pain of fighting to keep relic hardware working. In the end it's 100% user-choice and what they're willing to tolerate. In my case an unstable driver with no VDPAU is a definite no. I have no interest in dragging around dead weight. However, that tnt2 card may work great for you and keeping it might sound better then spending $15-$30 or more if you don't absolutely have to. Either way having a choice is better then no choice. :)

The Nvidia legacy drivers are kept up to date with kernel and X.org changes. Plus the interface between the binary blob and the rest of the system is open source, so in most cases anyone could patch it.
71.86.14 was released just a while ago with "Improved compatibility with recent Linux kernels": http://www.nvidia.com/object/linux-display-amd64-71.86.14-driver.html
For example my work computer had an ati card and fglrx support for it went away before warranty of the computer expired.
ATI has chosen a strategy of supporting open-source driver development so that they don't need to sacrifice as much resources on supporting legacy hardware.
Open source drivers are needed so that old cards can be put to use even after the manufacturer doesn't care to support them anymore.
I totally agree. It's good to have alternative projects such as Nouveau when the manufacturer doesn't want to release proper open source drivers.

Even though vdpau is open source, nvidia's support for it is propriety. To get any kind of acceleration would require the closed source drivers.
Have a look here : http://en.wikipedia.org/wiki/VDPAU http://en.wikipedia.org/wiki/Nvidia_PureVideo

The open nv driver doesn't even support Xv on modern cards, but you could try nouveau, perhaps.
