So this weekend I took a shot at geting vcr to work. I was unable to build
1.09 as the avfile snapshot downloaded from thier web page would not build
for me. As I recall, even after I ran the included autogen.sh script
configure still complained about missing files.
Haven't lpayed with avifile for a while, so I don't know what is wrong here.
So I wound up building 1.08. I was able to make this work, failry well.
That is using the DivX :-) low-motion codec and a resolutin of 384, I am
able to record. It dorps about 1 frame every 2 two to 5 seconds in capture.
I didn't worry a whole lot about this, since I am buying the parts to build
a gaster machine (1.2G Athalon) to actully deploy this, and I assume this
will at least take care of the droped frams.
A lot of what I want to record is fast motion (auto races), so I tried to
get the DivX :-) fast motion codec workign. Acording to the vcr web page,
this should work although the bitrate atribute can't be used.

Has anyone made this, or any other codec other than DivX :-) low-motion
work?
Don't know - it looks like you do not have the codec installed, or the
directory is incorrect? (The fast motion codec worked fine for me, but
under different software.)
Now on to playing. I decided to try mplayer, since it supports framebuffer.
However I was unable to get it to scale the resultant save files up to the
size I'm used to seeing them in fbtv.
Do I need to define a special mode for the framebuffer like i did for fbtv?
If so, can anyone send me a sample config?
The closet I have come so far to getting what I wanted here was to use -vo
xv, and scale the resultant window to full screen manualy, in X. There must
be a better way to do this, right?
mplayer uses hardware scaling when it is available - which is for "-vo
x11", and some cards with the fb driver (I am not sure which though). I
use "-vo xv -fs" to view full screen using hardware stretching.
PS. I understand that what I _really_ need to make this work is hardware
MPEG encoding. The WinTV PVR vard seems to have this. Is anyone aware of a
way to use this under Linux?
Hardware compression isn't really required these days - especially not
on a dedicated box. I have recorded a F1 race quite satisfactorily on
my 600MHz Athlon using software compression.
