Recording rule with "record all" ignores subsequent channels with the same call sign/channel name

[bearclaws8]

This instance of US OTA channels contain two channels with unique channel numbers (and service IDs) but the same call sign and channel name.

Problem: Recording rules for "record all showing" with "don't match duplicates" will show two schedule items but only record one instance of the show. Additionally, the user is unable to set up two separate recordings using the "this channel" filter. This behavior is new as of a recent (weeks or within a month) update and undesirable.

Expected Behavior: Until a recent update the behavior was for the recording rule to record the duplicate instances concurrently. This can be advantageous in cases where one channels signal quality is reduced while the other channel is not impacted.

User Workaround and Additional Info: Changing the call sign and channel name to unique values corrected this behavior (unsure which did the trick). With a unique call sign and channel name for every channel upcoming recordings shows two duplicate recordings instead of one recording.

Conjecture: It appears the recording rules migrated away from using the channel IDs and now use the call signs or channel names. This may be a similar issue or related to bug #12330. This may also be related to Changeset 43f9336f4d.

Changeset 43f9336f4d is about the name of the synthetic MPTS (full transport stream) channels which can be generated if the corresponding option in mythtv-setup is set. This is not related to the problem described in this ticket.

There have not been any changes in this functionality in serveral years. In addition, your version file indicates you are running MythTV version 29. That version has not had any changes at all in nearly a year. You are possibly confused by the MythTV feature which shows that a program will record on all channels with the same callsign. In nearly all such cases, it will only record on the single channel listed on the Upcoming Recordings screen. The only time MythTV will actually record on multiple channels for such cases is when there are guide data differences which cause the programs to be treated as different.
