Come on Terry, perhaps you should have sprted that out before you converted your shows to podcasts.
Just in case you are not the real Terry Wogan.... they will be played just the same as any other file given they are just an MP3 file like any regualr music file. The seceret however will be finding where they have been put, there doesn't seem to be a consistent naming format, the BBC for example either list the Artist as the Station Name but also some times the shows name.
Yes - I have no problem playing it back on my computer. It's just when I drop them into my mp3 player the message 'Error File' comes up and I don't know how to deal with it.
