6-1. Slow Loading Times for BD’s

Why does it take so long

to load my BD’s?

When a customer switches from one disc to another,

the lens have to be changed what causes the delay.

BLU-RAY require different lasers to read the discs.

Why does it take

so long to boot my BD?

The booting times for the BD is under 15 seconds.

When the set is booted,

it takes a little long time to loading the OS program.
