Yes, but it would be more annoying if it did not record anything.
Consider if the program guide changed and it thought
that there were two shows with identical titles and subtitles
but that one was 1 minute long followed by the second that was
29 minutes long... and then it recorded the 1 minute show
ignoring the 29 minute show.

Do you have lead in and lead out times configured? Hard lead
times change the length of the program and can cause scheduling
problems. Soft lead times can be truncated when there are

It could be. What has changed recently? It could be that your

Something to watch for is moving times. eg If what was an
8:00 to 8:30 program becomes an 8:00 to 8:29 program and then an
8:01 to 8:30 program.
