Wow.  Thanks for the info.

I think that I saw references to an S-Video/composite setting in the
driver control panel when I googled.  But there is none in the control
panel I have.

Actually, the ATI 9250 card was the last one with an open source
driver with acceleration.  So this is a plus for ATI.  I'm using the
open source driver.  There is now an open source driver with
acceleration for certain newer ATI cards but it is based on reverse
engineering, not specs, so it may not be as good as the proprietary
driver.  At least not yet.  Last I checked, the only open source
driver that could get anything out of the ATI X1000 family was VESA
and that only works for resolutions supported in the BIOS (precious
few and odd).

I doubt that the nv (open source) driver (with no acceleration) is any
good for watching MPEGs on a PII 866.  So I'm using the nvidia
proprietary driver.  Note: this is untested supposition.

My Athlon 64 x2 3800+ is using the nv driver and can display MPEGs
decently (with mplayer).  This machine has an nVidia 7800GTX, with
tonnes and tonnes (and Watts) of GPU goodness that I cannot get at
because I'm using nv.  How sad.  I don't want to be using proprietary
drivers unless I have to.

Why did I buy this fancy card, only to underutilize it?  When I bought
this system in January, the card was essentially the only
Linux-supported PCIe card that could support dual-link DVI.  Dual link
support is needed for my Dell 3007 monitor:  yes, the same one you
mentioned earlier.  Now there are $100 cards that would do (eg. ATI
x1300 with proprietary driver).
