This is a very common plea but, as I've said to others, I'm afraid it simply ain't possible to even have a stab at answering it without much more detail of your system, how it's connected up (i.e. which SCART socket on one unit to which SCART socket on another), and specifically what switch selections you're making. Sorry, but if we try to second-guess - and get it wrong - we could eaily make things worse, which doesn't help you.
Can you give the model numbers of the Sony Bravia (is that a TV, with internal Freeview?) and the DVD recorder (does that have Freeview, or an analogue TV tuner?) You mention a "format from the Sony website". Is that a connection diagram of some sort and, if so, can you provide a link to it?
I'm afraid I don't know what you mean by "the TV has 6 AV channels", are they perhaps analogue channels as well as digital Freeview? Nor am I sure what you mean by "channel 1 and 2". Is that BBC1 and BBC2, or is it maybe SCART socket (AV)1 and (AV)2? And I don't understand why you need to switch from AV1 to watch and AV2 to record. Maybe it's an odd, non-standard way of connecting Sony equipments, but from what you say, it sounds as if could be at the basis of your probs. Sorry if all this sounds in any way pernickety, but every scrap of extra info can greatly help.
