This is the first time i created a slide picture (vcd), so getting no experience at all before. I ran 2 tests to play the slide picture vcd on 2 different machines :

Test 1: Machine A
a)vcd player
b)vcd player audio-output plug in into TV audio-input

result : cannot hear the sound i add into the slide picture vcd when slide picture playing

Test 2: Machine B
a)Hifi with playing vcd capabilities
b)Hifi audio-output connect with 2 speakers

result : can hear the sound when play the slide picture vcd

My question after above 2 test

1) 2 different sets of playing machine and why only the machine B got sound when playing and machine A no sound come out when playing ?

2) Is it playing slide picture vcd must PBC turn on ? I use Nero vision express 2 create that above vcd but the PBC cannot fuction anymore when i use my remote control such as pressing faster forward, next, time search but the PBC is still on ? i cannot find the features in the nero vision express to create the fuctions of PBC? Any recommend software which can create PBC fuction ?
