#4778 closed patch (fixed)

Too many PAT/PMTs at start of file

[16135] Introduced BufferedWrite?() in dvbrecorder.cpp which causes a bit of a regression.

The new BufferedWrite?() in dvbrecorder doesn't honour _wait_for_keyframe_option or _first_keyframe < 0. This can result in HandleSingleProgramPAT/PMT writing (or buffering) too many PAT/PMTs to the file at recorder startup.

We only need one PAT and one PMT at the start of the file, not KB's of them. :)

The attached patch addresses this by using DTVRecorder::BufferedWrite?() in DVBRecorder::HandleSingleProgramPAT/PMT.

This patch works for me but needs review and testing in other scenarios.

(In [16385]) Fixes #4778. Only write PAT/PMT after once we start actually writing the video, to avoid a bunch of duplicates.
