For the TiVo, there’s a “Set Up a Manual Recording” option that has 5 fields to set:
How Often, Day, Channel, Start, Stop
Fields are initially populated by Once, [Current Day], [Active Tuner’s Current Channel], [Current Time rounded down to nearest half hour], [30 minutes after Start]
How Often can be Once or Every
If Once, Day can be any single date from current on forward
If Every, Day choices are Every day, Every Sun, Every Mon, Every Tue, Every Wed, Every Thu, Every Fri, Every Sat, or Every M-F.
WMC is quite similar, but instead of an Every M-F choice, there’s a “Multiple” option that lists the days with checkboxes next to each of them for even more flexibility. This can also be very useful as a workaround for series recordings that may yield undesirable results when left to automatic algorithms.
For the metadata, TiVo uses the guide data of the program that lines up with the start time of the recording. WMC doesn’t populate any guide information other than the channel and recording start time.
