do riteks 4x still burn on 1x recorder?
 

i just noticed that rima only sells 4x riteks nowadays, will that be a problem w/ my pioneer a04, which only burns at 1x atm, and if so...will they burn 2x no prob with my firmware upgrade?

Yes you can use 4x Ritek no problem but it is a waste of money. Get some 1x Ritek at www.meritline.com
