DTVRecorder: buffer up each payload until we know if the payload is a keyframe.<br>
Especially with H.264, we can be several packets into a payload before we<br>
know if it is a keyframe or just a frame or something else. Always buffer<br>
the packets of a payload until we know what we are doing with the payload.<br>
If we need to switch ringbuffers, we now do it so the new file will start at<br>
the beginning of the payload holding a keyframe. Each file will also start<br>
with a PAT/PMT if the "recorder" calls for it.<br>

decreases for me LiveTV experience on current 0.26-fixes.<br>
I see user experience regression in following 3 areas of LiveTV:<br>
1.channel change is slower (from 3-5sec to 7-10sec)<br>
2.on many channels, after changing to channel there is annoying audio stuttering for 3-4sec<br>
3.on some channels, after changing to new channel LiveTV "halts" on old channel. Switching to another channel helps.<br>
4.sometimes transition between programs on current channel hangs LiveTV.<br>
<br>
Without this commit, 2 is very sporadic and 1,3,4 seems to not happen.<br>
Above issues were so annoying that my hommies asked me to solve problem and reverting this commit seems to solve problem</blockquote><div><br></div><div style> I can see how the commit would contribute to #1, but it's hard for me to imagine why it would cause an additional 4-5 second delay. What tuner are you experiencing this with - HD-PVR?</div>
