In what order do files play when playing all recordings in this group.

I'm trying to figure out in which order my files will play when I play a folder.

Although the order of the files listed in the folder change when I sort by (season) or by (newest), the files never play in the order they are listed. The order in which the files play matches neither (season) or (newest). And the play order is not in the order the episodes first aired and is not in order of the file dates (which obviously changes when I edit out commercials before sending back to the TiVo).

As near as I can tell, maybe they're played back by the date on which they were recorded on the TiVo. As it happens the episodes were not recorded on their original air date. And they were not recorded in episode order (e.g. I may have recorded EP307 and then recorded EP102 and then EP401, etc.).

These files were all recorded on the TiVo Bolt, transferred to my desktop computer using kmttg and then edited to remove commercials (with VideoReDo) and then transferred back to the TiVo Bolt with pyTivo.

So, just what determines the playback order?

And for the curious... in this particular example the series is How the Universe Works as shown on the Science Channel.

Thanks
