Well, I still would like to know the URL because I like to observe
which set of URLs this eventually triggers.
I block with a URL filter some tracker URLs: URLs which are
unnecessary for showing video content but show the content provider
what you are doing. Sometimes these trackers cause hickups.
Any URL on the BBC news site which streams video will do it - e.g.
<http://www.bbc.co.uk/news/world-europe-14182135>
If you're lucky you can watch it all the way through - most times it stops
after a seemingly random amount of time, and displays the "twirling"
buffering logo. You might also then get something like "This content
doesn't seem to be working - try again later".
Bypass squid and it works every time - right to the end.
During streaming the squid access log shows lots of:

These keep running for quite a while even if the streaming has 'stopped'.
Videos from Youtube work fine (as do most other sites) - it only appears to
be the BBC videos that have the issue (or the BBC's iPlayer service - which
is UK only afaik).
Looking around the Web, I did find:
<http://old.nabble.com/RTMPT-fails-randomly-using-squid-proxy-td16570049.html>
I did go as far as commenting out the code that handled the "Suspicious
request - double CR detected" check, but that didn't make any difference
[in fairness I'd not seen any errors logged by squid about 'suspicious'
headers - but that thread does seem to be related to what we're at least
seeing].
I did do some packet captures - around the time things start to play up I
get a 'zero sized reply' error send from Squid to the client - but at this
stage I thought I'd see if anyone else had encountered the issue...
