Which keys are simulated?

[blagus]

When programming remote to region free Sony DVP-NS355, which key is simulated by entering code 189? Last key is power, with code 079. But which keys on original remote are asigned to keys 1 to 4 on universal remote? There's also some hex data like 0000 0068 0000 0015 0060 0018 0030 0018 0030 0018 0030 0018 0030 0018 0030 0018 0030 0018 0030 0018 0018 0018 0030 0018 0018 0018 0030 0018 0030 0018 0030 0018 0018 0018 0018 0018 0030 0018 0018 0018 0018 0018 0030 0018 0018 01ae

Which key is that?

Understand what am I saying?

Most hacks which require hex data, especially in reference to Sony products, can't be done with ordinary remotes. You need a special remote or laptop (or similar device) with IR port.
