Hey dude, I have tried many dvd witers like sony,gigabyte and tried many media like moser baer, optica, afa etc. However i find all dvds writen above 75% were faulty inspite of having the latest configuration using these dvd writers.
However when i lay my hands on Lite-on 1635s i was suprised.All dvds were written with out any fault. I used to get CRC error but every thing is fine now. Hence i prefer and suggest Liteon Dvd Writer.
Also read this months digit. Agent 001 Of DIGIT also suggest of Lite-On 1963s Dvd Writer. THIS IS MY PRACTICAL EXPERIENCE.
Also i suggest not to buy any optical drives from samsung. They tend to give many problems.Also the tray gets mis aligned very easily.
You can rely on me because i assemble and sell computers.
