can't extract anything with any program

[jfeynman122]

I've got a panasonic hdr212 tivo (US Stand alone unit) with version 
2.5.1-01-1-000 of the tivo software. I've tried using TyTool (alpha 
4), but its unable to complete a download of any show. I've tried 
downloading a 30 minute show that was recorded at basic quality with 
it, and it starts transfering the file, but then fails at a random 
point, then starts over with a new output filename. It continues this 
cycle until my hd is full of incomplete m2v files (also, after the 
first unsuccessful dl, it seems to put the audio data in the txt file 
and it doesn't create any new m2a files).

I've also tried using ExtractStream, but it either immediatly craps 
out or it grabs the wrong stream. sendstream v2 mostly works, or 
atleast the stream it sends is a fairly constant size. The 'actual 
yield'(that is, how much video zss can move to m2v before throwing 
the remainder of the stream in bad-X) of video after running zss can 
range from 5 to 25 minutes (with a 30 minute show). 

So far, my only successful process has gone like this:

1) find the id for the show I want to extract from the nowplaying 
page served up from http-tt.tcl.
2) run tivosh
3) dumpobj the id from step 1
4) dumpobj all part id's from step 3 (for a 30min basic show, its 
just one id. These have always been the id from step one with 
a /12,/14,etc on the end)
5) run sendstream -s "file ids from 4" | ./nc -n -w3 192.168.1.20 
11111
6) catch the stream on my linux box with ./nc -l -p 11111 > show.ty
7) use zss to split the show.ty into m2v and m2a
8) copy m2? to my win2k machine
9) use dvd2avi to make a d2v file from the m2v file
10) use tmpgenc to make an mpeg. 

When I used ExtractStream, I did the exact same process, except with 
ExtractStream in place of sendstream. 

So, what am I doing wrong? 

I also tried using tyc, but that threw a tremendous amount 
of 'Skipping chunk bad timebase', and the mpeg it produced wouldn't 
play in xine or win media player. I also tried using the hacked up 
mplex, but it failed to produce anything.

What I'd really like is a way to do all ty to mpeg/avi/rm conversion 
completely from the command line under linux with as little human 
intervention as possible. Has anyone managed to do this?

Or, at the very least, a way to get the FSID without 2 cut and 
paste's and running dumpobj twice?

Thanks, Jon
