Is fiber optic cable able to give you 7.1 or do you need hdmi? also can someone describe the difference between PCM and bitstream

Yes, it can. I don't know any movies or stuff that supports 7.1 yet, but it will. Your revievers built in DD/DTS decoder will process it if you have a 7.1 source. TMK optical/digital coax connot support lossless uncompressed bitstream (like Dolby True HD or DTS HD) because it is too large. But HDMI and 5.1/7.1 analog inputs can handle the larger uncompressed bitstream.

Basically bitstream will take the signal from source (like a DVD player) and send it to the receiver raw for the receiver to decode (either DD 5.1, DTS, Dolby True HD or whatever it supports). If you want your receiver to decode DD or DTS for you, you must use bitstream.

PCM (Pulse Code Modulation) , the processing is done form the source side and the player will convert everything to and output as 2 channel PCM.
