Incomplete Recordings

[iplayer at nutwood.net]

An overnight PVR run has left several TV recordings as mp3 files with no 
video. I am currently re-downloading them and all now appears to be 
going well.

I strongly suspect that something in my setup is the culprit as GIP is 
run on an old Windows 7 PC. Can anyone point me in the right direction 
as to what might be causing these failures?
