First off, I apologize for perhaps the poor summary. This is perplexing.

Single BE with HVR1600(tuner1) and PVR150(tuner2). Each card receives different input/different channel line up. Using Schedules Direct.

While recording with tuner1, and watching Live TV with tuner2, select the program guide. Each channel of tuner2 is listed twice.

For example - I was recording channel # 5 on tuner one, which is the same as channel # 13 for tuner2. While looking at the guidegrid during live tv with tuner2 I receive this information

.....
3 (tuner2)
3 (tuner2)
4 (tuner2)
4 (tuner2)
5 (TUNER1)
5 (tuner2)
.....
12 (tuner2)
12 (tuner2)
13 (TUNER1)
13 (tuner2)
-----

When a show is not recording, the program guide is as expected listing tuner1 then tuner2 data correctly.

I attached 3 screenshots. 001 and 002 are while recording, 003 is not recording.

It seems that checking for alternate channels based on callsign is broken as well.

[shane]

(In [22397]) Fixes #7276. Fix displaying of duplicate channels in EPG.

The main problem is that separate channels that share only the same channums are considered as possible alternate channels.

This patch changes this so that channels have to have the same channums and callsigns to be considered alternate channels in the EPG.

[shane]

(In [22398]) Refs #7276. EPG fixes for finding alternate channels by callsign.

Use the less stringent ProgramInfo::IsSameProgramTimeslot?(..) to verify alternate channels with the same callsign.

Channum Alternates: o same channum and callsign, guide content is not checked.

Callsign Alternates: o same callsigns and different channums, guide content is

checked for same titles and timeslots.
