Red face Nvidia legacy 71.86.13 and video playback to XVideo

Hello!
Before saying the word "problem" let me firstly thank nvidia developers for their respect to open-source community and for all the work they do with for us.
Now, that's what i need help for:
After i installed debian lenny and the latest legacy nvidia drivers (at first installed from the debian packages and then replaced by the official *.run), my video playback is slow, takes 100% CPU time and, if the video file is some bigger than eg 720x576, there arrive strange dots or bars in the video output. I've tried xine and mplayer, mplayer has a bit better peformance but it still doesn't reach the level on my previous install (it was debian etch with 71.86.01 nvidia driver) while the bars are still there.
I've made a photo of my computer's screen to demonstrate that (software screenshot didn't catch XVideo output).

I am using a relatively old machine (PII 350 MHz) with NVIDIA Riva TNT2 graphics card, but it still was able to playback such videos easily on the older system...
I attach several files, the names are self-explanatory.
Thanks for your attention,
Yury

Default Re: Nvidia legacy 71.86.13 and video playback to XVideo

do you need composite? if not, try to disable it so that the nvidia drivers uses overlay for xvideo instead of textured video

Red face Re: Nvidia legacy 71.86.13 and video playback to XVideo

I've already disabled it by adding the following to my /etc/X11/xorg.conf
Code:
Section "Extensions" 
        Option  "Composite" "Disable" 
EndSection
But i notice a strange thing in my Xorg.0.log:
At fist it says
Code:
...
(**) Extension "Composite" is disabled
...
But below:
Code:
...
(II) Initializing built-in extension XFree86-Bigfont
(II) Initializing built-in extension RENDER
(II) Initializing built-in extension RANDR
(II) Initializing built-in extension COMPOSITE
(II) Initializing built-in extension DAMAGE
(II) Initializing built-in extension XEVIE
(II) Initializing extension GLX
...
Maybe that could be the problem?

Also i've noticed that after installing the drivers, after X starts up the cyrillic letters on my /dev/tty* don't show correctly anymore. However if i boot without X, the fonts are ok.
What could that be?
Thanks in andvance,
Yury

Cool Re: Nvidia legacy 71.86.13 and video playback to XVideo

I have also noticed another important thing i'm not able to scale the video down! When i try to do so, players' windows just crop the video...
Of course, this happens only with XVideo output, but using any other isn't a solution in my case because of old CPU which really needs the video card's help.
When i used older drivers and kernel on my previous system, all seemed ok...
I just don't know where the change happened...

The only thing i can do is try to install the old system back and test it to see if it's really software issue, but i can't do this right now. However, i'll post here when i'll try that.
Thanks for reading all this,
Best wishes,
Yury

P.S.
I still love open-source!
