Downloading HLS streams from svtplay.se fails after random time.

[Hans Albertsson]

The below is a first attempt to report a bug possibly dependant on specifics of my network, and which seems to disappear when increasing the verbosity of ffmpeg.
Please tell me how to find more info if needed.

Summary of the bug:
How to reproduce:

ffmpeg -i "http://svtplay10i-f.akamaihd.net/i/se/open/20130510/1283828-004A/ENDEAVOUR_1-004A-8b76d2f9d0abebda_,900,348,564,1680,2800,.mp4.csmil/index_4_av.m3u8?null=&id=" -acodec copy -vcodec copy -absf aac_adtstoasc "Endeavour.S01E05.mp4"

Download occasionally works, but most times stops flat in its tracks after 1MB or several hundred megabytes or just before finishing or any other time.

It always works perfectly, at a slight cost in speed (5%???) if one presses '+' once, so that verbosity increases slightly, which then is a almost usable WA.

This has been verified to occur exactly the same on all my computers, Ubuntu 13.04 and Openindiana 151a7 and Windows XP. The WA is the same in all OSes.
It is also the same for the latest git-ed main branch ffmpeg (brought over yesterday and today, with identical problems. )
Note:
Increasing verbosity slightly also adds this to the output.
