Mux is short for multiplex. Each digital multiplex carries a number of different channels in the space previously taken up by just one channel on analogue.
DOG is Digitally Originated Graphic, so yes the logos in the corner of the screen are DOGs.

i kinda know what it is, but not too sure - is mux signaling and dog the logo?

I can't get Mux 2 at all, and have very weak signal for Mux A and particularly Mux B. It's all pretty darn annoying as they're all the good channels!
But we're getting a new ariel in a week or so, so that should help hopefully. Or is it just a London thing? I'm in outer North West London if anyone knows...

One thing I want to ask the people who have upgraded their aerial to improve reception - did you have to change your region to get all the muxes?
The problem we have here is that our main aerial is a communial aerial so we can't touch it really!
I've said this before but IMO I think it's time the muxes were reorganised slightly so that each had six channels (rather than the BBC having 4 channels on each mux then ITV/C4 having 8 channels on one mux) to hopefully improve quality on Mux's 2/A especially.
I also think the more prominant channels should get a slot on one of the first four muxes, while C4 should get their own mux.
I know whenever I post this people moan about the quality suffering, but to the general viewer (i.e. me!) I don't think Mux C/D suffered with the additional channels, while I think the benefits to channels on Mux2/A outweights the slight loss of quality of the BBC channels.
The other moan is regionality - but ITV and S4C manage fine on a mux of 8 channels so it shouldn't be a problem for BBC.
There are currently 36 channels, so they could easily put six on each.
I'd suggest something like:
Mux 1: BBC1, BBC2, BBC3/CBBC, BBC4/CBeebies, BBC News 24, BBC Parliament/News Multiscreen
Mux 2: ITV1, ITV2, ITV3, ITV4/CITV, BBCi 301, BBCi 302
Mux A: Five, Five US*, Five Life*, S4C/QVC, S4C2/ABC1/TCM*, ITV Play
Mux B: C4, E4, More4, Film4, E4+1, Quizcall
Mux C: Sky Three, Sky News, Sky Sports News, UKTV History, The Hits, TMF
Mux D: UKTV Bright Ideas/FTN, Ideal World, Price Drop, Bid Up TV, Top Up TV Anytime* (2 streams)
* Top Up TV currently has 4.5 streams. Two will be replaced by Five US and Five Life, while Top Up TV will close it's remaining channels and launch a download service which uses spare channel space overnight - so the two Top Up TV Anytime slots could be used for new channels, with Setanta Sports tipped to launch a subscription sports service using one of the slots.
It's not perfect, but it's better as all channels from BBC, ITV, C4 and Five are on the more widely received first four muxes - and reception on Mux 2 and Mux A should improve with the reorganisation.
At digital switchover each mux should be able to comfortably host eight channels. Whether though extra channels will be increased on a region by region basis as the analogue signal is turned off or wait until all regions have converted fully to digital is still unknown.
My personal opinion is it'll be the latter - and it wouldn't surprise me if the BBC are given additional space to run interactive coverage of the 2012 Olympics before the space is given over to new channels.

Yes, but the BBC MUXs use different modulation. The BBC MUXs use 16QAM, the ITV ones use 64QAM. 16QAM MUXs have a lower data rate than 64.

I can only think that 1 and 2 were originally the BBC and ITV/C4 muxes on On/ITV Digital - and the rest of the space, used for all sorts from Sky Sports to Carlton Cinema was on Muxes A-D.
It's only illogical if you let it annoy you. If you ignore it and accept it, your life will be much happier.

Could someone explain why the muxes are called 1, 2, A, B, C and D. Surely 1-6 or A-F would've been more logical - or am I missing something obvious?

Why is S4C in the channel five's multiplex? Why doesn't it replace channel four in te channel 3 / 4 second multiplex?

Because S4C Digital is a purely-Welsh, 12pm-12am (ish) channel, as opposed to S4C Analogue which is a mix of Welsh tv and C4 programmes. S4C Digital is therefore a purely separate channel. SDN actually stands for S4C Digital Networks, so they aren't on Five's Mux, they're on their own mux.
Therefore viewers in Wales can see C4 AND S4C Digital - two separate channels with no cross-programming.

What will happen to actual s4c when swich-over has happened?
