How to deregister my iPod from a computer I no longer have

You misunderstand.

Authorization has NOTHING to do with ipods.

You can authorize up to 5 COMPUTERS to play protected itunes content. You can sync as many ipods as you like.

There is no registering ipods with computers.

And you'll find more on authorization here: http://support.apple.com/kb/HT1420

I have got the same problem, my laptop crashed twice having to have new drive installed, itunes assumed I had got a new computer, did you get an answer to the problem ? would appreciate any assistance regards

Unless you get to deauthorize your computer before rebuilding or replacing it then the authorizations will accumulate. This isn't a problem until you get to five authorizations but want to add a new machine (strictly a new instance of an operating system). Once you get to five you can deauthorize all computers at once, including those you no longer have access to, and start over. In an anti-piracy measure you are limited from using this feature again for a period of 12 months, but can continue to authorize or deatuhorize individual machines up to the limit of five as often as you wish.

I'm in the same boat, all 5 computers are no longer accessible except the 1 I want to authorize. Looks like I have to buy all my music again...NOT, I'll just pirate them and prey!

I repeat...

Once you get to five you can deauthorize all computers at once, *including those you no longer have access to,* and start over.

I'll assume you've managed to keep copies of your DRM'd media and not managed to get yourself into the position where you need to deauthorize all within 12 months of the last time you did it. Is so it's all good. If not then in either case, and provided you haven't done it before, then if you approach the iTunes Store and explain the circumstances carefully and politely they may be prepared to either grant a second download of your purchases or perform an early reset of your authorizations.
