Rattle/Scratching Clutch/Flywheel., best i can describe as Options

[Goonter]

so when i start my car, usually on cold days, i hear kind of like a mix of scratching and rattling in the engine bay. I say scratching cause i found out that when i press the clutch the sound goes away. When I let go it comes back. Now this is only when i start the car and it goes on till i drive. After driving it's not present. Since the sound goes away when i press the clutch i was guessing somewhere along the "Clutch disk rubbing on the flywheel" area. Any input will be greatly appreciated thanks.

My clutch is also dying after less than one year, less than 20.000 km. It's been doing that every time since I bought the car, in 2008. Third clutch kit in 2 years, all of them different brands (first Valeo, then some F1 sports kit and now Aisin - which is also the original "equipment" as far as I know).
If I'm going to buy a new clutch kit, I really have to do something about the flywheel as well... the original, brand new flywheels costs a fortune, so it's out of the plan. An aftermarket sports clutch+flywheel kit would be also very expensive, since I'm planning an engine swap this summer (which would mean not being able to use the clucth/flywheel kit anymore). So, for a few months only, I want to choose the third way - repairing the clutch disk and pressure plate + remachining the flywheel. What I didn't understand - being the main reason for this off-topic reply - is: what is this "remachining" thing and what operations does it involve?
Thanks!
