 PC 1: Ubuntu. DVB-T card. mumudvb. UK terrestrial TV.
 PC 2: Ubuntu used for transcoding.
 (1gbps LAN)

 If PC 1 runs this ffmpeg command, it works OK and can view via  remote
 NGINX server. I watched for 30 mins with no problem.

 If PC 2 runs this ffmpeg command (across LAN from PC 1)  first few seconds
 seems to be OK, then many command line errors start, and keeps looping.
