Could you describe the details? (Whatever special you had to do, maybe
Modelines?) It appears from your description that I have a different Savage
2000 than you do (mine has 1 VGA outout and 1 TV-composite output, not the
2 composite outputs you report). But your experience may apply to other
Savage cards that do not have the xVideo defect that ours do.

Replying to myself..but I thought I'd add some details.

To use a Savage card with TV out, you *must NOT* have the X driver
option "UseBIOS" "off" set. It will not work. The default for UseBIOS
is on, and you must keep it that way.

Then, you can use the "s3switch" program (downloadable from above
website) to switch between TV, LCD, and CRT outputs. This uses the
video BIOS to do the switching, so it really ought to work for all
boards.

If you're having problems, it's probably a good idea to download the
latest version (1.1.27t currently) of the driver from the website. This
is newer than the version included in XFree86 4.2.1.

Until the next version is released, you may have to apply the following
patch to make s3switch work if you're using a Shuttle SK41G (this patch
came from the author, so I assume it'll be included in a new version at
some point):

Heh, maybe my original post was unclear, I have 2 of the cards, not a
card with 2 composite outputs. I didn't use any special modelines, I
was incredibly impressed that it just worked under X. I used it in a
freevo box for arond 3 months, using X11 as the output for mplayer. I
decided to switch to MythTV because it has a better feature set than
freevo and I bought another savage 2k card in anticipation of this.
However, once I installed MythTV I discovered that I required XV
support in order to function and so I pretty much had to mothball those
cards and go looking elsewhere for my TV support. The second card I
bought was slightly different than the first, but the TV output works
great on both of them under X. They are both generic Savage 2K cards
with 64 MB of memory.

If the Savage IX chipset will work under Linux for TV out and XV, there
are cards with S-Video out for $12.85 at
http://www.compgeeks.com/details.asp?invtid=ASVGB1N-8MTV.

Here are my experiences with the various cards I have:
S3 Savage 2000 64MB Composite out - See above
ATI Radeon 7500 Svid + Composite - No luck. Works in console mode but
scrambles under X. The atitvout program did not work for this card.
Maybe with the ati.2 branch?
ATI Rage 128 SVid + Comp out, Comp in -- No luck, maybe with the ati.2
branch?
ATI Rage II+DVD Svid + Composite -- WORKING! See
http://www.retinalburn.net/linux/tvout.html. Black border around picture
NVidia GeForce3 Ti 500 -- TV-Out working with drivers from NVidia's
website. Black border around picture.

I have a Savage IX card that I bought for $8 for use in my MythTV. I followed the directions on that website that dlou posted: http://www.probo.com/timr/savage40.html I then dpkg-reconfigured xserver to use the savage driver. Then at the console, I used "s3switch tv" to switch to the tv display. I could not do TV and CRT at the same time, but that was alright. Jee

Waitasec. What about this?

http://www.probo.com/timr/savage40.html

As a matter of fact, I have a friend who set up
his Myth box with the Savage/IX and TVout to his
antique 53" NTSC big screen. As a matter of fact,
he's
on this mailing list. Jee, care to share your
experiences?

Therefore, if there are multiple encoders, a higher value may be
