Embedded in the tyDirs are the tyDbs. This is where the real data is actually hiding out.
While poking through the MFS [Hack #88] you are inevitably going to run into objects. The objects, or tyDbs as they are called, are the database objects holding the real information that the filesystem directories (tyDirs) are just organizing into a simple hierarchy.
You can peek at an object using the TiVo shell's dumpobj command. dumpobj does exactly as its name suggests: reach into the MFS database for a specified filesystem ID (FSID), extract appropriate metadata, and dump it to the screen in human-readable form.
Let's take a look at a rundown of the first television show in my /Recording/NowShowingByTitle directory. From the TiVo shell (type tivosh at the Bash prompt if you're not already in tivosh), run it on one of your FSIDs, like so:
% dumpobj 1717520
Recording 1717520/10 {
ActualShowing = 1717520/16
BitRate = 0
Bookmark = 1717520/19

Out comes all the attributes associated with this television show. Notice the title fragment "MTV MOVIE AWARDS" (/Recording/NowShowingByTitle/1:2003 MTV MOVIE AWARDS), the number of seconds I've already watched (NSecondsWatched = 3539), and other assorted details.
It's also worth mentioning that our friend TiVoWeb will do the same thing. Use the web-based MFS browser to click your way to one of the tyDb objects, and you should see something like Figure 7-2.
That said, if all data about the show is in the MFS database, where's the full title of the show? The guest stars? Television channel from which it was recorded? If you look closely at the object dump, you may well see what appear to be FSIDs; in fact, that's what they are.
This is where the TiVo shell and command line has one leg up on TiVoWeb. You could go through and dumpobj each of the associated FSIDs, but you'll no doubt find even more to comb through. You could also click through on TiVoWeb, but that is just going to get frustrating. There is a short cut: dumpobj takes a closure flag, telling it to dump all the FSIDs it finds along the way, starting with the FSID you provide. It's a long list but a pirate's booty of information:

The Program node (FSID 1691635) holds the title and full description of the show. The Station node (FSID 2086) tells us that the show was recorded off MTV. And that's absolutely everything TiVo knows about the object we asked for. The question is, what do you do with it? See the following hacks for some answers.
