Programme name missing sometimes on latest Git verison

[M Clark]

Using this Git version, 17/12/14 18:01, the programme name is not always in the downloaded file.
e.g.
Andrew Marr's History of Modern Britain - 3. Paradise Lost, BBC Two, Factual,History, default
is saved as Paradise_Lost_-_3._-_b007n1dx_default.mp4

Secrets of the Castle with Ruth, Peter and Tom - Episode 5, BBC Two, Factual,History, default
is saved as Episode_5_-_5._-_b04v4vmg_default.mp4

25 Years of Rock - 1970, BBC 6 Music, (similar for 1971, pid b04v5q71)
is saved as 1970_-_16._-_b04v5n90_default.m4a

Rockin' Around the Christmas Tree - Episode 1, BBC 6 Music, (similar for Episode 2, pid b04v5qcd)
is saved as Episode_1_-_1._-_b04v5n92_default.m4a

These are my examples, if there is anything special about them, other downloads fine (e.g. Newsnight_-_17_12_2014_b04v4k80_default.mp4 and Gideon_Coe_-_Nic_Jones_in_concert_b04tqg4s_default.m4a).

WebPVR on Vista (tried get_iplayer on lubuntu, loads cache okay but displays zero programmes so 'parked' it for time being).
