The latest episode of one of Tony Robinson's "walks" is scheduled as one of a series of Tony Robinson's Coast to Coast, but turns out to be "Walking the Thames" the first in a series "The Thames: Britain's Great River with Tony Robinson" according to IMDB, and looks to have been first screened by Channel 5 as recently as June this year.
I'm not suggesting a name change for the series by IceTV because it is in the OTA EPG as Tony Robinson's Coast to Coast, and changing it mid-stream as it were would be confusing for folk who, like me, use both IceTV and OTA EPGs for scheduling recordings. I just note it here for accuracy.
According to IMDB and the Channel 5 website "The Thames: Britain's Great River with Tony Robinson" has four episodes. Having seen the first I would like to see the other three screened by SBS, but knowing the potential for confusion in that neck of the woods it is also possible that they screened the wrong program last night. I think it less likely, as acquisition and screening of such a recent program would in all likelihood not have been a mistake. Fingers crossed.
