best results for dvd-r

We've tried burning with several type of media on the market and none failed here are the results

MAGIC brand 4X : best media ever made over 50 attemps at 2X
( 2$ each) using alcohol120% none failed you may find
this valuable blue bottom packed media on
the market
MAGIC brand 2X: also made over 100 attemps with rec. now max
(1.7 $ each) and about 50 with alcohol 120%
some failed with rec now max it's taxing to burn
with rec now max last party media on the
market were bad so try 4X instead
our new tried media are dms 4X,princo 4X,focus 4X
we burned new releases LOTR return of the king,fifa 2004,wrc 2 xtreme with success 4cos(www.4cos.com) is a bit nifty but works like a charm

we use pioneer AO5 with both 1X,2X (2X is better)
we burned all games up to date with success
use alcohol 120% for better results (or wait ages with rec now max ...we burned 4.04 gb of - lotr return of the king pal- image in 20 minutes at 2X using alcohol)
we tested with 300004 v4 pal with star modchip and 390004 v7 with messiah 2 pro 1.33 (latest ver) none failed.. we were waiting for your comments and we are ready to advice on problematic games' burning ...
