Definitely get what you are saying. However, and I am sure Simon can correct me if I'm wrong. I belive the sub channel, as in the. 1 part of the 5.1 signal is totally separate and so not affected by active crossovers. To explain what I mean a little better imagine this. If you had a separates system and you unplugged all the normal speakers but left the sub plugged in you would still get the sub sounds for all the channels as it's fed by a separately encoded channel.
I know this is a hit of a change of subject but I was just looking at videos on YouTube. We all know the surround does not work at all well on there. However I just found this on there
It says it's an Lpcm 5.1 test. Strangely it works perfectly with all channels separated. I have no idea why. If you have the YouTube app on your TV can you give it a try so I know I'm not going mad. Lol.
Yes, I'm really confused by that. I tries looking at the specs of the clip but can't find what's special about it. Another Obe for Simon to solve as I also only ever get stereo with fake surround from you tube. Why can't all you tube vids be like that one. Would make viewing trailers ect much much better.
