thanks Marni for that, only just seen this post, Had a similar problem with a different setup. When i had my original Tivo I used to supply and old TV in my conservatory using a wireless sender from the scart socket. Obviously when my new V6 box was installed i lost this facility. I also at the same time bought a Samsung 5500 series Tv to replace the old conservatory one. The only way i could get a signal to it was to use a HDMI splitter from the box to supply my lounge TV and i installed a Cat 5 cable to the conservatory and used HDMI over ethernet boxes.The problem i now had was the Samsung didn't see any signal and the only way round it was to switch on the lounge tv and the Samsung then got a picture, i could then switch off the lounge Tv and every thing was ok I've been playing with this for a few weeks and counldn,t find a way round it. i read your post and thought i would try it and it works!!! What I would like to know is why it works. because that setting is for the digital tv settings not the HDMI Thanks again.
