I'm new to TiVo hacking. Just installed 80Gb Seagate U6 drive and
TiVoNet. After fighting with lost connection to TiVo for a week
(daisy-chaining a switch and hub messed me up) I have been fighting to
extract mpg's to my linux server for the last week. What a pain!

1. ExtractStream package (.2) didn't work for me.
2. esdirect/mime-type/netcat/netmplex wouldn't work. I tried it all
the various ways of setting up streaming, and it would just hang.
3. CVS version of ExtractStream (.3) works, but the httpd.tcl has no
recorded shows
4. ConvertStream doesn't work for me (I'm at TiVo 2.0.1).
5. Finally! got nfs mounting to work. A little documentation would have
been nice. It's for mounting remote server's filesystems on the TiVo.
6. So I just set up ExtractStream to go to my nfs mount:

# TiVo Hack!
[ -x /tivo-bin/hostname ] && /tivo-bin/hostname quicktivo
/bin/bash </dev/ttyS3 >& /dev/ttyS3 &
if insmod -f /lib/modules/8390.o; then
insmod -f /lib/modules/tivone.o
sync; sleep 2
ifconfig eth0 192.168.1.4 netmask 255.255.255.0 up
route.tivo add default gw 192.168.1.1
[ -x /sbin/tnlited ] && tnlited 23 /bin/bash -login &
[ -x /tivo-bin/tivoftpd ] && /tivo-bin/tivoftpd &
[ -x /hack/bin/httpd-tt.tcl ] && /hack/bin/httpd-tt.tcl &
# For ExtractStream
insmod -f /lib/modules/nfs-2.0.1.o
mount -t nfs 192.168.1.1:/var/tmp /mnt -o soft,bg
export AUDIO_OUT=/mnt/tivo.m2a
export VIDEO_OUT=/mnt/tivo.m2v
fi

7. I compiled TiVo's mplex for x86, and it ran, but lost the video
stream.
8. A ha! A clue! mjpeg-tools has a working mplex for linux:
mplex -m2 -b 200 -o movie.mpg movie.m2a movie.m2v
9. my normal players on linux (dual p2-375) have trouble playing it
(dvdview, xmovie, vlc) but there is no audio sync problem.
10. "mpeg2divx -a 192 movie.mpg -o movie.avi" works, but is even more
unplayable with aviplay. lost frames and motion artifacts. It is
however 1/10th the size! Optimum settings anyone?
11. move to 1.2 GHz athlon/Win98SE - both files play great. I use the
Sigma Hollywood Netstream2000 mpg2 decoder and bsplay divx player. Full
screen mpg2 looks better than on my hdtv. Even the highly compressed
mpg4 is ok - better than a vcd.

The netstream2000 was made to play network streaming mpg2's. I eagerly
look forward to that functionality on my TiVo.
