I'm having a similar problem on a few week old Sony 2.5.1 SA box 
(not DTivo). About half the time I can successfully extract data, 
but the other time it's a total failure with almost identical 
messages to what you report.

I've gone so far as to get a linux build environment for the TiVo 
setup, and modify the ExtractStream source to try and see if the 
calculation for FSID->physical offset is off, but no success yet. I 
also wrote a small app that waits for a TCP connection and then 
fufills requests for arbitrary size and offset data from /dev/hdXX. 
(The theory here being to write applications to browse the raw 
contents of mfs disks in DevStudio instead of the whole cross-
compiler dealie). 

I've posted a few times here recently (browse back the archive like 
10-15 messages) but you're the first person to report similar 
problems.

I'm wondering if it's only occurring on new/factory 2.5.1 machines?

Let me know if you figure anything out; I'm (...ok, my wife is...) 
anxious to start archiving to SVCD :) 

I'm also keen to write a small TiVo app that does the tyConvert 
thingie on demand served up over HTTP so I can watch MPEG streams on 
my computer while she watches TV or other previously recorded 
programs on the TiVo.
