Sony KDF-E42A10 HDTV Pioneer Elite VSX-82TSX Receiver HD Tivo Series 3 Oppo 970HD-DVD Velodyne CHT Front Row Speakers (5.1 only) AV123 X-Series Sub Last weekend my system worked perfectly. My set up was Tivo and Oppo- components & RCA plugs to the TV for my wife and TV speakers use and HDMI for Tivo & Oppo through AVR for me and movies. No problems. I had an x-series sub on order from AV123. I received that yesterday. In the meantime I ordered a set of 5-RCA Component A/V Cables. I also ordered another new heavy duty HDMI cable (I already had 2 hooked up and working and ordered the 3rd for DVD to AVR). Anyway after adding the new cables and sub, I lost the ability to use the HDMI from my Tivo. I have tried everything, including going directly from Tivo to TV. Nothing. I tried using the old cables, nothing. The DVD works through HDMI, but these new cables seem too stiff. (This is now not true, I can't even get the DVD to work using HDMI) Add the fact that the sub is making the speakers Hum like a mo fo, and I want to cry. (I have determined that the cause is the cable from the cable TV, this did not happen with my old sub which was part of a HTIB) I am ready to pack the whole thing in a sell everything. My wife brought up the old "remember how happy we were with out old 24" TV and no stereo" thing. I have been in contact with Tivo-no help I have done several reboots of the Tivo with no success. I am aware of the firmware issue with my receiver but I actually had my receiver upgraded with the latest firmware. The thing that gets me is it worked fine before. Now not even with the original cables.-Scream! I am going to strip it down tomorrow and start from scratch, but I am not optimistic. What could I have done to screw it up so bad?
