Frequent need to repair disk

My MacBook Pro (17" 2.33 Core 2 Duo) frequently requires disk repairs (booting using the install CD and using Disk Utility to repair it).

Frequently as in once every month or two. I don't understand why. I've been a Mac user since way before OS X, and on no computer with X have I ever had to repair my disk, much less once every month. My usage habits are no different on this machine than any other. I do lots of video, film, and graphics work.

Here's a console dump of the disk utility's diagnostic today. They are usually similar to this, mentioning bit mapped errors.

Disk Utility started.

Verifying volume “Macintosh HD”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.
Checking volume bitmap.
Volume Bit Map needs minor repair
Checking volume information.
Invalid volume free block count
Invalid volume free block count
(It should be 6266676 instead of 6245785)",2)

The volume Macintosh HD needs to be repaired.

Error: The underlying task reported failure on exit

Disk Utility stopped verifying “Macintosh HD” because the following error was encountered:

The underlying task reported failure on exit
1 HFS volume checked
	Volume needs repair
What does this even mean?

I gotta ask the dumb question -- have you booted from the OSX DVD, and Repaired these problems? (they cannot be repaired when you are booted from the disk that needs repair)

Just gotta establish that its not the same problem, being reported over and over.
