Understanding Future Schedule, Refresh Cache, Exclude Programmes

[MrArtist]

Hi,
After a long time using an older build I finally updated to the August 
2011 one via the Windows installer and also worked out how to update to 
the latest patch builds (.pl & .cgi) which was a lot easier that it 
first seemed (just replace the text file!)

I'm using Get_iPlayer on Win7 64bit via the Web PVR interface and love 
it, especially now that I can use "Exclude Programmes" from the list 
which brings me to question 1:

1. I have a longish list of comma separated programmes that I exclude 
from my web page view. When I look at the PVR list, that long list takes 
up a lot of space on the page view. Is there any real need for that 
exclusion list to be carried over into the PVR list? I have solved the 
visual problem by manually editing each PVR Search name and removing 
that line so now my PVR list view is a lot more compact, but I wonder 
why it's needed, or if there can be an option to turn it off? Same could 
be said for the Exclude Channel which also doesn't seem to be useful in 
the PVR list.

2. Regarding the Refresh Future Schedule, when I activate this, I now 
get about 1,200 programmes showing in my Search list, without it I'm 
down to a manageable 300 (after using my choice of Exclude Programmes). 
I see Channel entries for all regional areas such as BBC One Channel 
Islands, BBC Two Northern Island, etc., and also BBC HD. - Also there 
seems to be lots of programmes that I might not normally see (I might be 
wrong there) such as Family Guy which has loads of entries, presumably 
all upcoming (future) and none when I look without Future Schedules 
activated.

What I'm wondering is, by not selecting and looking at the Future 
Schedules, am I potentially missing out on ever seeing some programmes 
come up? i.e. will there be things listed regionally that won't come up 
via the standard view of BBC One, Two, Three, Four? - Or is it usually 
the case that only the first showing instance of a program is shown and 
sometimes that will be listed regionally as opposed to the more general 
BBC One type listings? e.g. I see the odd few BBC HD listings in Future 
Schedules, but none in the non-Future Schedule listing, is this because 
it is shown on BBC HD first?

Lastly, I also note that for the regional listings (e.g. BBC Wales, NI, 
West, etc), the Categories area is blank. - is this normal? In 
non-Future view, I always get a category specified.

Many thanks
