Comment(by simonf):

 I know this may be a silly question but when the back end is asked to
 start recording the new program, on a program break, is it seen as a full
 request IE does it retune and resend the channel info to the demuxer. if
 this is the case certain chanels with a low signal would take longer to
 lock. (especialy with dvb) I remember when I unchecked  "Wait for SEQ
 Header" I also made a new video source for each of my tuners one tuner in
 particular took a long time to lock on Channel5 uk DVB-t so i removed that
 transmitter from the video source for that card. Also I bought a 3 way
 ariel amp and all the dvb cards have there own signal input before the
 signal used to go into one card and out then into the next card. This
 reduced the number of artifacts (blips) on the screen, dvb is very
 sensitive to poor signal strength. One thing that realy does show this up
 is to reduce the signal time out in the scan to say 1.5 seconds 1500ms and
 do a scan for channels without the booster i get 2 muxes (BBC ones) and
 with it i get all the muxes. (QED) thus if it does do a retune / re-demux
 every time it gets bo a program break it would take over 1.5 seconds to
 relock. The other thing i find interesting is that a) some of us have
 problems which manifest themselves more on given channels and b) some
 people dont have the same problem running almost identical/ identical
 hardware and ditros thus surely the problem has got to have something to
 do with eiter the setup or the boxes environment eg  the signal strength
 etc.
