Hi
If you goto
http://gradius.rpc1.org/ you'll find a f/w patch that not only makes it region free but also riplock Why?
Basically your107 is set to a region & locked ( locking means the drive will rip at say 5x>8x ) Manufacter's do this they say to cut down on errors
Unlocking a drive lets it rip at say 6x>12x or even in theory 6x>16x depending on the drive ( difference 12x &16x on typical DVD is only about 30 sec as the high speeds are only peaks )
So if your happy with the 107 you can upgrade f/w make it region free + riplock thereby improving it's flexability & performance
Originally people used a reader + a writer because of cost, now alot of folk's use two writers
At present as far as I know ther is no f/w available to do this on the 109
This is not the case with Nec there are several patches around even for the latest drive 3540a
The LG 4163b like any other dvdrw can be used as a reader or writer ( although there are patches to make this region free )
ther is no riplock as far as I know (meaning ripping speed 5x>8x )
For writing either the Pioneer or the LG would be fine
But for reading if speed is important to you, you'll be better off with either a riplock or aDVD Rom
As your happy with your 107 I thought you could try the f/w unlocking it & concentrate on getting a dual layer burner
This would mean saving some pennies ( as you'd no longer need a DVD Rom ) or you get a more exspensive burner
Difference 109 /XL try this
