The model of Integrated AV Amplifier: TA-VE150 (Sony). When i connect my dvd player with the 5.1ch output to the amplifier, to the 5.1ch input, my subwoofer is not playing (or i thing the sound is very very slow) With the DVD 2ch connection it works fine! (from the player to the DVD 2ch of the amplifier. At the DVD player menu i have these: Analog Out Digital Out AC3 2 channel (or 6 channel) PCM RAW or Off DTS off (don't have dts on the amplifier) Raw When i choose the 6 channel option the digital out is going off. Also, in the Menu "More Audio" i have these: Prologig=ON Subwoofer=ON The player contains a dolby digital (AC-3) decoder. And the amplifier manual say's that if i have a dvd player with a dolby digital (AC-3) decoder i can connect it.
