Thanks Declan. I did check out RTE today.
Managed to download both episodes 1 and 3 of what iPlayer calls sessions series 3 (but then when they launch they become series 4!)
Tried repeatedly to download or even play epsiode 2 but "there is a problem, try later".
To clarify the rules re iPlayer (as there seems to be some confusion above!):
You can watch things for up to 7 days after the tranmission if you DON'T download the programme to iPlayer downloads. (the exception being, as with Transatlantic Sessions, if the BBC decide to make all episodes of a whole series available for longer)
Once you have downloaded a programme to iPlayer, you have it for UP TO 30 days, BUT!!! - once you start watching it (even if only for a few seconds!)you then only have 7 days to watch it before it self-destructs.
If you forget to watch it at all, it will self-destruct after 30 days.
You cannot record from iPlayer to DVD using the BBC technology.
See above for Nick's method.
