umm who told you it was fragmented?
As a rule the filesystem Tivo uses doesn't fragment.
it's not an issue like it would be on a windows PC

Yeah, I hear it doesn't fragment, too. But what is it that seems to degrade over time? I know previously people would point to the number of shows in the NPL you would accumulate etc., but when I went to 6.2 all my speed problems went away. Now after months of using it, while maintaining an NPL of about the same size and with about the same number of SPs, it's gotten bogged down again, though in different places than it did with 3.1. All that has changed is the shuffle of programs in and out of the NPL and the deletion and addition of SPs. It sounds like a fragmenting problem, doesn't it?

Edit: Oh, yeah, and rebooting doesn't really help.

How many Season Passes and auto recording Wishlists do you have?
How many recordings are in the Now Playing List?

This is the order of things to try.
1) Restart/reboot
2) Reset Thumb Ratings $ Suggestions
3) Clear Program Data & To Do List
and as a last resort
4) Clear and Delete Everything

These options can be found under the Restart or Reset System Menu.

Read the warnings for #3 and #4.

It IS a hard drive, after all. You're recording, deleting, modifying... I don't see how it could NOT get messy after a while...
It does get somewhat fragmented, but not nearly as much as Window's systems. Also, the linux OS, which is a basis of the TiVo, can do some cleanup on its own as required. Others can explain in more detail if needed.

my tivo unit has a a dvr player. When I placed a DVD into the unit, the tivo unit went into a continual reboot. When I called TIVO, I was told that the tivo unit loads a portion into a cache file, and if the disk is too fragmented, rather than being able to load it, it was kicking the machine into a reboot.

I was told that a badly fragmented disk would result in this behavior. I had to manually extract the dvd from the the reader before tivo unit would boot up

Actually, linux file systems can become fragmented, however due to the design of the filesystem, they tend to be more "fragmentation resistant" than Windows filesystems. Here is a simple explanation of the differences between Windows and Linux files systems:

http://geekblog.oneandoneis2.org/index.php/2006/08/17/why_doesn_t_linux_need_defragmenting

If your DirecTIVO is hacked, and you can open a command shell, it's easy to tell how fragmented your file system is - use the e2fsck command (found in the /sbin directory on my DirecTIVO, might be someplace else on yours). If you don't know the device names of the partitions on your disk, use the df command.

Here are the e2fsck results from the two partitions on my DirecTIVO:

/dev/hda7: 2489/32768 files (1.5% non-contiguous), 79893/131072 blocks
/dev/hda9: 4365/32768 files (12.2% non-contiguous), 41855/131072 blocks

As you can see, the first partition on my DirecTIVO ("/") is 1.5% fragmented, which is not worth worrying about. The second partition ("/var") is 12.2% fragmented, and if I was really worried about it, I could probably go track down and install one of the linux defrag tools to clean things up. But, my DirecTIVO runs fine, so I think I will leave it alone. :)

If you do some google searching with the keywords "linux filesystem fragmentation", you'll get more information than you probably wanted...
