Subtitles Round 3

[Peter S Kirk]

XP Chrome gui

Tried patched .pl with:

Beechgrove Garden E23 gave a 0kb .srt with both old and new

Gardeners_World_-_2013_Episode_24
Old gave 11kb .srt which missed when speaker changed
New gave complete 43kb .srt

Question Time 26 Sep - Tried new only and all perfect. That was a good test 
as many changes of speaker and very fast changeovers.

QT needed a 3.5sec subtitle advance in VLC to sync - is that get_i, vlc or 
bbc problem? I'm running it through handbrake to see if it syncs subs

Great work Dinky, much appreciated

Cheers
