Query: Great for PC,forget about DVD Player,XBOX, PSP etc.

For budget PC speakers these rock. For most normal Human Beings this PC speaker set should suffice. Clear Sound, excellent Bass.However for DVD Players and XBOX you need to buy an adapter which Logitech claims "will convert it to 5.1". If you have a look at the instrument and its two Stereo RCA inputs you will realise the converter is Crapware that just gives you the same sound from Front and Rear speakers. Don't even dream of hooking it up to your DVD player for a surround sound expereience.Also the US version only accepts 110 Volts and not the 220 Volts Indian/British standard.
