 Hi

 vpid/vPID actually stands for "version" PID; 
as you say, it denotes the PID (Programme 
IDentifier) for various available programme 
versions, all corresponding to the same "mother" 
PID, i.e. iPlayer show - the vpid string is used to 
retrieve available streams via (various) 
"mediaselector/5" URLs.
 As such, vPID isn't associated only with video 
programmes, but it's used for radio, too. 
For radio it used to be that only the "default/original" 
version was offered, but due to recent audio factory 
changes, many (mostly spoken content or other 
for which more relaxed rights apply) radio shows 
have got a "podcast" version, too...
