[mythtv-users] Poor-Quality SVCD's

[Tom Purl]

I'm trying to export some of my MythTv shows to SVCD's using
nuvexport, but the qualityy is really poor.  It's *very* pixilated, to
the point where images are blending together.  Since the .mpg files
that are created by nuvexport look just as bad as the actual svcd's,
I don't think the problem is with anything outside of nuvexport.

I'm using ffmpeg, which I compiled from source.  Here's how I
compiled it:

    FFmpeg version SVN-r6335, Copyright (c) 2000-2004 Fabrice Bellard
      configuration:  --enable-mp3lame --enable-libogg --enable-vorbis
    --enable-faad --enable-faac --enable-libgsm --enable-xvid --enable-gpl
      libavutil version: 49.0.1
      libavcodec version: 51.15.0
      libavformat version: 50.5.0
      built on Sep 26 2006 21:16:44, gcc: 4.0.3 (Ubuntu 4.0.3-1ubuntu5)

Also, here's what I get when I run nuvexport with the --debug option:

    --------------------------------
    To encode:  Scrubs:  My Fruit Cups
    Use the following commands:

    system call:
    mkdir -m 0755 /tmp/fifodir_5807/

    forking:
    /usr/bin/nice -n19 /usr/local/bin/mythtranscode --showprogress -p autodetect -c 1047 -s 2006-09-23-14-00-00 -f "/tmp/fifodir_5807/" --honorcutlist 2>&1

    forking:
    /usr/bin/nice -n19 ffmpeg -f rawvideo -s 480x480 -r 29.970 -i
    /tmp/fifodir_5807/vidout -f yuv4mpegpipe - 2> /dev/null |
    /usr/bin/nice -n19 yuvdenoise 2> /dev/null | /usr/bin/nice -n19 ffmpeg

    yuv4mpegpipe -s 480x480 -aspect 1.33333333333333 -r 29.970 -i --aspect

    10 -cropleft  10 -s 480x480  -b 2500 -vcodec mpeg2video -qmin 5 -ab
    192 -ar 44100 -acodec mp2 -f svcd '/home/tom/test/Scrubs - My Fruit Cups.mpg' 2>&1

Does anyone know what I'm doing wrong or if there are any good
alternatives for someone who wants to burn recordings to a CDR (since
I don't own a DVD burner)?

Thanks a ton in advance for any help!
