My guess is the problem lies with 'continuous' type of livetv file
transitions, these continuous transitions are used for livetv ivtv
files but not V4L or DVB files. The discontinuity (discont=1) type of
file transitions follow a different path and are ok I think.

Should be able to test this theory by making a small code change in
tv_rec.cpp ...

Around line 1310 in TVRec::RunTV(void)
+ SwitchLiveTVRingBuffer(true, true);   // Try this for discont transitions
  - SwitchLiveTVRingBuffer(false, true);

I also have a vague suspicion that something else might be causing
more prebuffering pauses than usual.
