It's 0.1.10-pre2, but without any of the ck patches (Chris is currenly
on 114f, so there have been a *lot* of interim versions).

You have the TCL 2002N tuner. This tuner is not supported by the tuner
module included with the Linux kernel. Therefore, you need to patch your
tuner module to get access to all your channels.
Unfortunately, patching your tuner module will probably require you to
patch/re-compile/re-install your tuner module. Whereas Axel Thimm has
packages available for Fedora Core, I don't know of any sources of
patched modules for Debian. (Any Debian packagers out there who want to
make some available????)
The patch you need can be found at
http://www.poptix.net/ivtv/Sep-2004/msg00773.html . You will need the
patch for Linux 2.x (either 2.4 or 2.6, depending on your kernel
version). Note that there are five patch "files" on that page
(ivtv-0.1.10-pre2-ck100z, ivtv-0.1.10-pre2-ck108j, linux-2.4.27, linux
2.6.8.1, and a video4linux snapshot releases), so make sure you take the
appropriate parts (look for the filenames in the lines starting with
"diff -Naur").
Once you patch your tuner module, you can simply specify:
options tuner type=50
and continue using ivtv 0.1.9.
If you prefer to upgrade, I recommend ivtv-0.1.10-pre2-ck100z with the
appropriate patch from the same page as the Linux patch. Note that if
you're using Linux 2.6, you may (depending on how your kernel was
compiled) also need a patch for the use of sys_* calls (
http://www.poptix.net/ivtv/Sep-2004/msg00829.html ).
