Apple :: File Permissions Stuffed

I some how managed to completely screwup the file permissions ownership on my macbook (10.6). This seems to have also mirrored itself to my timemachine. So I did a clean instal of SL, and then manually moved my files from TM back across, but unfortunatley the permission for all said files are wrong.

So I went as set using cmd+I the permission to myself as owner, as checked to apply to enclosed items, thinkin that would do the trick.

Unfortunately while it did fix a few files, the majority still remain stuck with the "_unknown" as the owner, which is preventing me from opening and using pretty much everything on my mac.

Does anyone know a way to force write the owner permissions to me for ALL files in my home directory?

I have tried the repair permissions in disk utility several times, it does nothing
