[Kwintv] Still scaling problems.

I have been evaluating the X server from SI Graphics (it runs for 25
minutes for the eval version)
I find that xawtv and other xv tv apps will scale to fullscreen with it.
I then switch to the XFree server that came with RH8 and it doesn't
scale.
Looking at the xawtv -hw output on the RH8 server:
This is xawtv-3.74, running on Linux/i686 (2.4.18-14custom)
looking for available devices
port 59-59 [ -xvport 59 ]
type : Xvideo, video overlay
name : video4linux
port 60-60
type : Xvideo, image scaler
name : ATI Radeon Video Overlay
/dev/video0: OK [ -device /dev/video0 ]
type : v4l
name : BT878(AVerMedia TVCapture 98)
flags: overlay capture tuner
The SI Graphics server:
This is xawtv-3.74, running on Linux/i686 (2.4.18-14custom)
looking for available devices
port 85-85 [ -xvport 85 ]
type : Xvideo, video overlay
name : BT878(AVerMedia TVCapture 98)
port 86-86
type : Xvideo, image scaler
name : CODEC
/dev/video0: OK [ -device /dev/video0 ]
type : v4l
name : BT878(AVerMedia TVCapture 98)
flags: overlay capture tuner
It looks like the XI server correctly uses the BT878 directly.
It looks like the XFree server is using video4linux (which I believe
doesn't scale).
So:
1) I don't think its a hw problem
2) I don't think its a kernel problem
3) It looks like its an XFree problem
4) but it might also be related to the BT drivers not "telling" XFree
about itself correctly
I guess I'll try to download the latest XFree (groan......)
