I'm trying to get a reasonable DVD/TV output, and I'm having flickering 
problems. I captured a PAL VHS source using a DC10+ and 1.6.1. My MJPEG file 
has these attributes:

--DEBUG: [lav2yuv]    width:            768
--DEBUG: [lav2yuv]    height:           576
--DEBUG: [lav2yuv]    interlacing: top field first
--DEBUG: [lav2yuv]    frames/sec:    25.000

Following the HOWTO, I tried encoding to DVD acceptable format using this:

lav2yuv _30secs.eli |
yuvdenoise |
yuvscaler -O SIZE_720x576 |
mpeg2enc -f 8 -q 7 -4 1 -2 1 -P -I 1 -N -o dvd_30secs.m2v

Which I understand denoises leaving the interlacing in place, then encodes the 
interlaced source. Played on my DVD player and 50hz TV, it's horrible. The 
content is a yoga style video, which has slow (to non existant :o)) action 
and a pure white studio background. The background flickers terribly, and the 
edges of the person and equipment are ghosted and flickery.

I tried adding -F to yuvdenoise and -I 1 to mpegenc, understanding this would 
deinterlace and produce deinterlaced output, and should therefore look bad on 
my TV. Actually, it looks a bit better, but is still not really usable.

Any clues? My suspicions fall on the yuvscaler, which isn't described in the 
HOWTO, but appears to be necessary. (The example in the HOWTO gives an error 
message for me without it.)
