two dvd drives region info

on my dvd 's drives that i bought it says in current region not selected
but i am able to play region 1 or 2 since it says current region not selected
will the disc quality not be as good or will it be the same if i select it to 1 or 2

since it plays all regions but in properties were is says current region it says not select if i do not select a region does that mean my computer will play the disc in lower quality

On my Liteon iHBS 112 ODD, the user changes left is 5 ( No region selected by the user) Does it mean it will play any region disk? The answer I found is NO.

When I tried to play a multiregion (2,4,5) disk, Windows Media Player said that the current system region is set to 1 and I should set it to 5 to play.

So what turns out is that the vendor has set it to Region 1 leaving 4 vendor resets still available. If it is not a region 1 disk the user has to set the region. ( The ODD was imported from ebay, USA)

Quality does not depend on region code, which only determines whether it plays or not on your system.
