FWIW I've also written a simple (ROX filer) front-end that lets me drop a file onto it which lists the PIDs and my chosen transfer methods. [snip] > ...

FWIW I now leave the relevant machine fetching in parallel with watching or listening to something as I eat breakfast. I use the same machine to fetch as I do to play the results into the TV and audio setup. It seems happy to spin both plates at the same time when this is needed. > I sympathise for anyone in your situation where you have constraints on > your downloading schedule, a real hassle. Well, I can download things during the day. But as you'd expect, getting the 'hd' TV files can rapidly add up. So by default I try to fetch TV files before 9am. That usually gives me 1 - 2 hours. So it is mainly a matter of being organised. ( Not my best suit! :-) ) However at present I'm trying to keep up with the Proms. One of my most 'busy' periods for TV. I am coping so far. Just spend a while going through the proms on tv webpage choosing the pids for the next few 'morning batches'. > > > > This does drift OT.

Yes. That's what has put me off it! I did some years ago write a cross-correlator program to do a time synch measurement of the offset between bbc iplayer and freeview files. Did this to get results I put on the web at the time. Part of an early comparison of TV versus R3 for the Proms audio. So I could revive that and have a go. But not a trivial task. As a result it has been for some years in my box marked "awaiting a supply of round tuits"... :-) But the current problems brought it back to mind. May find it useful sometime.
