I hate that too! There is no reason it should dump the buffered material just to start a recording. On the other hand, I have had the opposite occur too, for what every reason I had "Office Space" set to record around 2 in the morning on Cinemax, what actually recorded was about 20 minutes of a soft porn show that was on prior, very surprised a few days later when I went to watch it and it started playing something like "space sluts from outerspace"?? I'm not a prude but since it's a premium channel, I can't download load it and clip the porn out so I left with leaving it the way it is or deleting it and record it again the next time it's on. Not sure what went wrong, the schedule time for the movie was correct, it wasn't as if the last 20 minutes of office space was clipped??
