I have seen this before. If I delete a program while another is recording, then the show that is being recorded will have the chunks missing exactly as you describe. My workaround is to only delete when nothing else is recording. my best non-technical guess would be that drive intensive activity during recording will cause this.  I've always meant to try the "delete files slowly" option to see if that corrects it.
