Looks like we have the same issue I reported for Radio 4 a few weeks ago, this time with BBC Parliament:
http://www0.rdthdo.bbc.co.uk/cgi-perl/api/query.pl?method=bbc.schedule.getProgrammes&format=simple&detail=schedule&channel_id=BBCParl ... has been returning "Error: Code 152 No matches found" for the last couple of days at least. Cheers, Mario.
