Are you using a single display or a dual display? Do you see other X applications slowing down when they try to display something? With the 8xxx versions of the Nvidia driver, it can take up to five seconds for an xterm to display one new character when mplayer is running on my system. It's like using a 300 baud modem. Shocked

Dual display. I've never noticed any problems with slow X.

Everything works normal when I have HDTV playing, I can even drag the mplayer window around between displays. Also I've used other versions of the nvidia driver with no problems. I don't seem to be having any of the problems you guys are reporting - until now I didn't even know it was an issue.

It's a PCI XFX Geoforce FX 5200.

Does this happen to you only with XvMC or when playing any video?

If everything is slow, but otherwise works, it sounds like your bus is getting overloaded. Do you get any kernel messages? What bus is your card using?

Try also setpci, with the latency_timer command. It's been a while since I used it so I don't remember what to set it to, but it can give the video card a higher priority for bus traffic.

As per above, I reverted to Nvidia 7676 and am a happy camper.
It requires a bit of ingenuity to compile it against a 2.6.16 kernel or 2.6.17 kernel, but nothing too bad...

Say, could you help out a dude that doesn't possess this ingenuity you're talking about? Very Happy

I'd love to try out one of the 7xxx drivers but naturally it won't compile.

To build the Nvidia driver 7676 with kernel 2.6.17
  1. Edit nv-linux.h to turn off NV_POWER_SUPPORT_APM
    (or whatever it is) regardless of config settings.
  2. Modify Makefile.kbuild and add this in row 78 (all on one line):
    Code:
    EXTRA_CFLAGS += -DNV_SIGNAL_STRUCT_RLIM -DNV_PCI_GET_CLASS_PRESENT -DNV_REMAP_PFN_RANGE_PRESENT

  3. Run the installer
  4. Move installed 'modules/extensions/*' and 'modules/drivers/*'
    from /usr/X11R6/lib to /usr/lib/xorg.

You'll need to rebuild mplayer against the new drivers.
With luck, you're good to go.

Bob deinterlacing went into mplayer SVN recently.
It doesn't look like they're doing field dropping, though:

Also, someone on the devel list reported an av-sync problem:
http://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2006-October/046684.html

It's a shame--the patch I got from this thread works pretty well AFAICT.

I'm surprised it got commited. The maintainer of the XvMC part of the code was clearly against adding anything like this and for reasons that were just wrong (frame rate must be doubled so mplayer can do "work" between field displays, code probably doesn't do anything anyway). It seems like he had only used XvMC to watch movies on DVDs and never seen 50/60hz video before.

It's not even clearly why the maintainer relented. Of course the last thing these guys ever want to say on the development list is "Sorry, I was wrong."! Very Happy
