I hadn't previously heard 'clean feed' and 'dirty feed' referred to in the context of playout tapes before.
Distribution master tapes from programme-makers are usually delivered with the entire programme, followed by a section of 'textless material': anything which would have a graphic on it, without the graphics (and usually in silence). The main programme material will have the final mix audio on channels 1 and 2, and a 'music and effects' mix (ie no voiceover) on 3 and 4.
A clean feed from a broadcaster will normally be just the programmes, with no trails, interstitials, or DVEs. In the BBC's case, long blank gaps between programmes are filled with a slide of the BBC logo on some clouds.

Cool, thanks. How about A-Roll, B-Roll etc? I have a fair idea of what they all mean but a concrete explanation would be much appreciated.
A clean feed in a presentation perspective would be taking a source feed, say directly from an OS, where a dirty feed would be taking the feed from, for example, the transmission output.
An example of a dirty feed would be a news programme showing a recording of a football match taken from either off-air or a feed of pres.
There's another definition of 'Clean Feed', one not connected with tapes:
When a programme does a live 'down the line' interview or 2-way with a reporter or guest, the audio in their earpiece is known as 'Clean Feed'. It is the programme sound minus the audio from the line - so the reporter/guest doesn't hear their voice come back in their ear.
In some places this i known as IFB - Interruptable FoldBack

If you don't mind me asking, what job are you going for?
No problem asking. Not going for any pacific job at the moment - still a student, but have done a bit of Work Experience around the industry. Just really keen to learn more about everything TV - the whole clean/dirty topic I've had some limited understanding of for a while, but wanted to nail down the facts so thanks for that - it's much appreciated
Yep feeds like this are out there, for example with a Scottish Premier League match on 10E, there is a dirty feed with Setanta's scoreboard, commentators and visual effects, and a clean feed, with no scoreboard, commentators or visual effects sound, you just get to see the transitions, it's all very interesting, enough to get myself a motorised dish one day.

Yes, very interesting - I would never have imagined so much from off-air would be kept. So...
After a show has been TX'd - you have a master copy, an off-air copy recording what has actually being broadcast and not just what the gallery has recorded, clean copy, dirty copy, A-roll, B-roll etc (still not absolutely sure what the differences are between all of these - would be great to have someone clarify ) and all the individual VT's which were transmitted - correct?
Any idea of what would be kept from a live broadcast with regards to rehearsals and the like? So basically when everyone at home would be seeing VT's on-screen the gallery would have a seperate tape with everything going on in the studio too.
