rather than going for a HTIB, go for onkyo or a similar setup wherein you can attach any DVD player. I have a Sony HTIB since last 4 years and the DVD player is giving me problems. now the amplifier is inside the DVD player only, so for a 5.1 channel sound I have to play the DVD in the DVD player, which is not working properly...the speakers are working fine but can't get a new DVD player.
also this one has a two channel Audio In at the back, currently i route the audio from my PS3 in two channels to the DVD player...only if i had something like Onkyo S3000, I would have had more flexibility with my sources and maybe speakers too....
What i am trying to say is complicated. Please feel free to ask for any clarifications..
