<< so you need a av pack for 5.1 dolby digital, and the remote control to play dvds?? or are they one and the same? >>
no, the DVD kit contains a USB infrared sensor and a remote control only
the A/V pack(either Advanced or High Definition) provides a connection for optical digital audio connection, but the optical cable itself is not included (just the connector for optical cable) <-- this is true for the advanced pack... i am not sure if the hi-def includes optical cable or not... I presume it doesn't
