other is MSI DH22a9p both are DL burners, and i'm having problems reading a DVD, it's an HP lightscribe type disc DVD-r, no more info on it.

i've burned them with nero 7 ultra with the LG drive on my win XP machine then after a year it don't want to read it, bought the above mentioned MSI drive and it won't read even on win XP or win 7.
currently only the MSI is connected since i only have one IDE plug
ideas ?
