Comment 0 for bug 35794

When using Xorg on a Trident CyberBlade/i1 with a TV encoder (VT1621 (both
NTSC and PAL), Xorg fails to use a working TV display. Here's the setup:

Epia 800 (lspci output attached)
FC2 (Xorg 6.7 (version output attached))
Samsung Plano TV

Before going further about the bug, I want to first thank you for the work you
guys have done for this driver and Xorg in general. It's fine and I want to
help make it better.

Now, the Epia BIOS and jumpers are configured to output PAL. So console mode
works fine with the TV. Meaning, until I start Xorg, I can succesfully use the
TV and the display works fine with all the normal console stuff.

Once I start Xorg, (i've appended the various xorg.conf's that i've tried),
the display goes swizzly (noise) for a few seconds and then blue screens
indicating that the TV doesn't like the input. But Xorg is active and believes
that it has successfully controlled the display (according to Xorg.0.log).

I then tried a patched trident driver from Alastair Robinson at
black5services. This also failed to get the TV display on init, but when
combined with TVtool (run from the shell to set the tv output manually) (also
from Alastair), I was able to get a working TV output at 640x480 (log files
attached). I was then able to use most applications cleanly. However, mplayer
playing content in xvidix mode exhibited a narrow noisy band on the right hand
side of the TV (likely related to bug 431).

I'd be happy to help debug the issue. I will set up a Xorg build so that I can
build the trident driver and test any changes. But I'm not too knowledgable
about the driver details so I will likely need advice and directions.

Here's what I'd like to solve with respect to this bug:
1. Get Xorg to succesfully use the tv output (merging back the changes from
black5's code and removing the need for tvtool?)
1a. Get Xorg -configure to generate the correct config for TV output if TV
output is selected

2. Support mplayer XVIDIX correctly. Currently, using the black5 driver, I get
a noisy band at the right hand side of the TV. This noisy band looks very much
like it's coming from what should be a narrow band on the left hand side of
the screen. Perhaps this is related to bug 431 filed by Richard Pinnell about
this same driver.

Okay. I really hope that you guys might be available to help direct me towards
fixing this. I'm happy to spend time on this.

Thanks,
Melkor
