There are still five episodes left to be broadcast - one every day this week (at both 6:00am and 3:30pm) and one next Monday (same times).
Whether they've just managed to inadvertently swap two episodes in broadcast order or not, I don't know. Really, it looks like my main concerns are episode 1 (which presumably went out last Friday, or possibly Thursday - my copy is only about 11 minutes of a 23-ish minute programme), episode 4 (which, as far as I can tell, I'm missing entirely), and episodes 6 & 7, both of which are truncated by a few minutes, but nowhere near as badly as episode 1.
So, one way or another I should be able to plug most of the gaps in my collection - and hopefully the fact that it's getting this repeat run bodes well for possible future runs... It'll just be interesting to see which episode they show tomorrow...
