Not sure a flow chart would help either my wife or my daughter particularly.

Lets see:

1. There are the new digital tranmitted channels that the TV picks up on its own.
2. There are the normal terrestrial channels (for a while anyway) that are also dealt with directly by the TV - both coming from the antenna on the roof - wife and daughter manage these fine.
3. There are the channels that come from out interent provider via the ADSL line through a separate reviever connected via Euroscart to the TV.
4. There is the Wii box connected to the TV via RCA's - composite and left and right.
5. There is the DVD player connected to the TV via Component plus left right audio.
6. There is the WD HD box connected to the TV via the HDMI cable and separately connected to the stereo for left right audio.
7. Connected tot he WD HD box are 2 hard disk drives - both 500 GB. One is powered and the other takes its power from the USB port itself. The powered one is used for archiving mainly whilst the other is portable so that I can copy content from the computer as the need arises. Actually the other drive can also be connected to the computer via USB by simply plugging it in to the 10 meter long cable I installed for the process.
8. There is the video recorder connected 2 way via a Euroscart connector. The video audio output is connected to the stereo - allowing anything playing on the TV to come through on the stereo except for digital inputs which the TV refuses to decode for some reason.
9. Connected to the third input on the VCR is the CD player (as I have run out of connections on the pre-amp and accompanying extension box).
10. There is the Computer directly connected to the TV (setup as a second screen - an extension of the first screen) via VGA at 1680 (?) by 1076 which is enough for 720p but not 1080p that has to come via the WD HD box. The sound output from the computer goes to the externsion box on the pre-amp so the TV cannot play the sound from the computer - it has to come from the stereo, uniquely.
11. In parallel the antenna is also connected to the radio (1970's panasonic unit with great sound) via a signal booster (the TV signal also passes through this) and that is connected to one of the inputs on the pre-amp extension box).
12. Directly connected to the pre-amp is the TT - via the external phono-amp.

Of course things are not really as simple as they appear above.

The computer is networked with my wife's computer (a netbook) and an Ubuntu server. Content can be on any of the hard disks on the network (of which there are 5) - although actually most content exists in 2 locations on the network for security.

Then there are the rules:

1. Digital music on CD is played from the Marrantz CD player as it sounds so much better than the Pioneer all in one DVD.
2. All other forms of digital on disk (SACD, DVD, DVDa etc.) are played on the Pioneer.
3. Digital music (soft) comes from the network and from the WD box unless it is loseless WMA in which case the WD doesn't support it. FLAC and MP3 can come from anywhere but only if using the VLC player - the Windows media player doesn't support FLAC.
4. Digital video in HD form @ 1080p comes only from the WD.
5. Digital video in HD from @ 720p can come from either the WD or the computers if the sound-track is not DTS which the WD cannot translate to its analogue outputs.

Actually there is a bit more desides - like the connections for my wife's phone, my phone and my daughter's MP3/4 player but I doubt anyone has followed me this far.

Isn't everyone's system like this by now? I just counted the power connections behind the TV - so not including the Computers - 18 items plugged in!

I am not even sure I can account for them all.
