I haven't seen it before either. But MC does some really neat things with consecutive recordings if you use the JTV file format, and I wouldn't want to see that functionality broken while trying to fix a cosmetic issue.
For example, MC using JTV files is the first PVR/DVR hardware/software I have used that can record consecutive programs and create two recording records in its database with all the meta data for each program, so that you can watch either at your leisure, but at the same time shares the "overlap" portion of the recordings rather than duplicating the recording in files that fill a hard disk, and honours the padding on each recording, and (optionally) starts playing from when the program should have started not at the beginning of the padding time, and doesn't require another tuner for the second recording, and possibly other good stuff I have forgotten. WMC may have come close to that, but I didn't use it long enough to remember.
The only strangeness in this functionality is that the two programs will likely be stored in the one folder, and that folder will be named according to the first program. That can make moving and renaming programs a bit of a challenge, but even that still works.
At this time I consider MC's TV functionality to be a bit like that eccentric, nerdy uncle we all have, who is sort of neat to have around, but you have to forgive his strange habits and foibles.
