Hi Jim,
I tried this as the simplest place to start and have made no progress. 
Also tried using Winff GUI and I think I need guidance on codecs etc. if 
you are willing.

To start at the beginning and why this is on GiP list is that all the 
problem downloads are from GiP and are BBC 3 classical music downloads 
such as The Early Music Show or Opera on 3 and they are mostly "hi fi" 
stereo or supposed to be!

The problems I have date from the various times when my GiP setup was 
flawed or atomic parsley not installed, all through my ignorance.  They 
fall into two categories, those that play but must be played from 
beginning to end (no time markers,) and those which do not play at all 
and stall the control app.   (I am using BubbleDS control app and Linn 
Majik renderer playing files served by Minimserver from NAS.)

The files are delivered by my GiP setup as .m4a files and there is no 
video but there is usually a thumbnail and useful metadata about the 
particular recording which I would like to retain.

The simple command with ffmpeg you gave above halved the size of the 
file but it would not play.  I tried various other variations, some 
using winff GUI but none worked.

If you or others have time I would appreciate some further help and it 
may be appreciated if I went off group or started a new thread until I 
can announce success!
