GOD i hate this minimum time between posts !!!!
anwyasy here i type again sigh
dont go for samsung
samsung sucks
samsung gives tray problems
most forum members will tell u the same
no offence to dr grudge
go for lite on drives .. they are the best .. unless ur gettin a dvd iter then dont get a lite on go for pioneer
dont go for combo dirves they do have a failure rate
also its better to have a separate writer and a separate dvd rom
all dvd players play all the formats ... atleast the new ones ...
the problem comes if u write a dvd on one drive .. it might not be detected on another companies dvd rom or dvd writer
but this is rare
dvd 5 /single layered single sided = 4.7gb
dvd 10/single layered double sided = 8.4 gb
dvd 9/double layered singlesided = 8.4 gb
for dvd 10 the data is written on both sides of the disk and u have to flip the disc to read the other side
dvd 9 does not require flipping
this is the only diff between the 2
for more on dvd formats
