Question about mfs_extract and tystreams

[pokemonrdobh]

My tivo is a DirectTivo Tivo. I've used both extractstream, and 
mfs_export on the tivo to extract. I don't have a ethernet connection 
so I've rigged up a ppp connection via the serial port of the DTivo 
and a linux host. There was an issue with bad fsid's when using 
extractstream, is was due to the mask used in a calculation for fsid 
to raw sector. I think this was solved. I'm thinking this same 
aproach might need to be taken to sendstream. From there (ok this is 
getting lenghy now isn't it) I've ran across a util that was being 
worked on another board. This one parsed the output of both the files 
generated from mfs_export and extractstream. I've also revied the 
code as best as possible on both. I liked mfs_export's medhodloghy 
since it didn't play the stream again then grab the output from the 
codec, it just dumped the data out of the mfs constructs. In any 
case, the parser that was partially developed seemed to be the only 
one that could remotly find intelegent life on the data generated by 
either extractstream or mfs_export. To perform the tystream to mpeg 
conversions I've used both windows 98 and Linux hosts just depended 
on the utilities available for testing. I'm tried tyc on the linux 
side, I've tried splitstream 0.5 and tyconvert on the windows side. 
I'll take a second gander at sendstream and see what pans out. BTW 
does anyone have a PPC compiler ? Just incase we need to make a DTivo 
version of sendstream.

if it helps I have a 700mhz linux host with 256mb ram and a 900mhz 
windows 98 host with 512mb ram, and my poor tivo is running a 72mhz 
PPc with 32mb ram and a WD60gb drive with 2.0.1. tivo/linux o/s.

Thanks
