Can I downgrade to Tiger and restore data using Time Machine?

I've been having some funny problems lately.
Im experiencing problems with my optical drive including burning CDs and DVDs and I even had a problem reading my Mac OSX install disc 1 while I have been contemplating a downgrade - It would tell me that i inserted a blank DVD. Well i put in disc 2 and it seemed to read that ok, so I tried disc 1 again and now i'm able to read it. I'm going to try a hardware test now that I've got the disc..

I've also been experiencing some latency issues with GarageBand and Logic:

and I'm getting the feeling I have a lemon of a MBP..? Or Leopard Issues?

I'm curious if I can do a clean install of TIGER and use my time machine backups to restore data and apps?

Or any other recommendations?

Thanks!!!

MBP, 2GB, 2.2GHz, 10.5.2

 

Thanks very much for the replies!
As I suspected...

I have ben reading other posts and I understand that it is possible to to a clean install of Leopard with my Leopard DVD and then restore my data AND apps with my Time Machine backups? That I will be prompted during the Leopard install to do such a restore?

Thanks!
