Thanks guys. Where do I start: Well you see my computer system setup. I use Sony Vegas 4 to capture & edit my Dig8 movies. Then using Mainconcept MPEG encoder, then TMPGEnc to author DVD, finally NERO6 to burn the files. My home theatre is a sony HTDDW870 H/T in a box. I have DVD hooked to the receiver Audio using COAX, Video using RCA jack, and also have analog audio hooked to the receiver using RCA jacks. The TV is hooked to the receiver. DVD is Toshiba SD3109, which has An optical & Coax O/P, also has 5.1 channel O/P audio AND it also has 2 channel audio out. Anything else you need. I have hooked the analog audio from DVD to receiver from the 2 channel. The receiver manual states that if I chose 7 setup the Audio input at AUTO the system will detect and play accordingly, but does not work for my home movies. Any help and ideas suggestions would be greatly appreciated.
