Quicktime plays in an unfinished HLS event playlist cannot

Question

I have an HENT playlist of type EVENT. It has the tag #EXT-X-PLAYLIST-TYPE:EVENT . Playlist is not completed. It does not have the tag #EXT-X-ENDLIST .

When I play a playlist in Quicktime, it does not allow me to search. Since this is an event playlist, all previous segments are available. Quicktime should have everything you need for your search.

I tried this on OS X 10.6 and Maverick, and a problem arises. I also tried this on an old iPad running iOS 5. On iOS 5, the problem does not occur.

Here is the playlist itself:

 #EXTM3U #EXT-X-VERSION:6 #EXT-X-ALLOW-CACHE:NO #EXT-X-MEDIA-SEQUENCE:0 #EXT-X-PLAYLIST-TYPE:EVENT #EXT-X-START:TIME-OFFSET=0,PRECISE=NO #EXT-X-TARGETDURATION:10 #EXTINF:10, live_robocop_hd-rate_01_6512.ts #EXTINF:10, live_robocop_hd-rate_01_6513.ts #EXTINF:10, live_robocop_hd-rate_01_6514.ts #EXTINF:10, live_robocop_hd-rate_01_6515.ts # ... more segments here ...
