It is particularly annoying for me that it has arisen during the Proms. On one hand, using the 'old' (RTMPDump/Flash) route is markedly slower. Since I mainly get things before 9am to dodge using up my 'allowance' this limits how much I can get at what is a 'busy time'. On the other, if I use the HLS I have to carefully check to see the result is complete. I am also now worried by the possibility that some examples I've not yet fully watched might havs problems at some point with synch, etc. i.e. It may not be sufficient to ensure they seem about the correct length. Particularly annoying for a musical concert where synch is vital. If there is a synch problem due to missing chunks at some point, does that persist or accumulate to the end of the file? i.e. if the synch is correct at the end, does that indicate that it was probably OK thoughout? To make things worse, the Lumpits mean there won't be any Proms on broadcast TV for a few weeks, so iplayer is the only access for the TV versions. This does drift OT. But it has reminded me that one long-term wish/thought I've had is to work out how to take an iplayer TV version of a Prom and replace its audio stream with the 320k R3 version during the music. However even if I knew how to do this, again I think synch would drift. Tests some years ago showed clock drifts between TV and radio.
