Hello,

How is the program guide sorted? Everything was fine when I only had one tuner, but now that I have added an HDHomeRun tuner to my setup all of the new HD channels are scattered throughout the listings. I would like the similar stations to be listed together. I.E., the 2.1 HD channel to be listed right after channel 2, etc. The listing are sorted by the Channel number in MythWeb, but not in the FE program guide or while flipping channels.

Please tell me there is something I can change to get the channels sorted in some logical fashion.

Ok, when I change the guide to sort by channel name it sorts correctly by the callsign ID: WBBM, WGN, etc. However, when I change it to sort by channel number, this is my current channel lineup:

All of the X.Y channels are tuned from my HD (technically a "digital", not just HD) tuner and the others are from my SD tuner. As you can see, this makes for some interesting channel surfing. This isn't even sorted by frequency ID. I can't really make heads nor tails of why the HD channels are just scattered throughout the SD lineup. And even some of the SD channels are out of order. Take a look at the channels after 49. What's up with that?

Are there any suggestions on how to get things sorted correctly?

And as I mentioned in my first post, the MythWeb listings are sorted correctly. IE. 1, 2, 2.1, 3, 3.1, etc.

Same for me, the channels are in perfect order in the channel editor and mythweb, and all whacked out in the frontend. If I go into the channel info in Mythweb I get another different order, it is a hybrid of the two, sorta messed up but not as bad as the frontend. There is no discernable pattern as far as I can tell, really weird...
Frontend looks like this:
0, 1, 2, 2.1, 3, 4, 5, 6, 6.1, 7, 8, 9, 10, 10.1, 10.2, 11, 12, 14, 15 through 32 in correct order, 10.4, 103.5, 106.1, 113.7, 12.1, 13, 12.2, 13.1, 18.1, 2.2, 32.1, 32.2, 33 through 99 in correct order, 32.3, 6.2, 7.1, 74.7, 8.1, 8.2, 8.3, 82.6, 82.7, 9.1, then back around to 0.

Mythweb channel info shows all the analog tuner channels first in correct order up to 69, then goes 0, 71, 98, 70, 99. Then the digital HDHomerun channels go:
2.1, 8.1, 8.2, 10.1, 10.2, 12.1, 32.1, 32.2, 2.2, 8.3, 32.3, 74.7, 6.1, 82.6, 82.7, 103.5, 7.1, 106.1, 6.2, 9.1, 12.2, 13.1, 10.4, 18.1, 113.7.
This ordering is the order the channels are in on the digital cable feed.

I know it's possible to sort it correctly as mythweb and the channel editor get it right. I'm thinking it's a bug at this point unless someone can figure out some pattern to this order I am missing. The mythweb channel info makes sense because it's in the order of the digital cable channels, but I can't figure out a relationship between that and the frontend order. Like why to 2.1 and 6.1 go in the correct spot while 8.1 is at the opposite end? And what is going on with 32 and 12 and 13?

Have either of you removed/re-entered your tuner information in mythtv-setup since adding the new tuners? Sounds like the order may be following the insertion of the subsequent tuner cards...

I haven't "re-entered" any tuner information. This just happened when I added my HDHomeRun to my existing system. However, I am going to completely changing out my tuner cards this week, so I will get another shot at configuring the channel lineup.

However, I am interested in what you might be thinking the problem is. All of the digital channels (2.1, 3.1, etc) are from one tuner, while all of the standard channels are from another. There is absolutely no overlap in channel tuning. I would be perfectly happy if the channels were sorted buy tuner and then by channel number. However, the channels are not even sorted that way. I have looked at all of the various fields in the "channel" table in the mySQL database, and can't find any reasoning behind the current sort order.

At least I'm glad to know that I am not the only one experiencing the issue.

I don't know that there is any specific sorting order. I do know that I am using PVR-350, PVR-150 and Fusion HDTV Lite cards on a R5D1 + .20 system and I don't see this behavior. All my tuners were setup/configured at the same time, whereas the problem you are seeing seems to have occured after adding additional tuners to an existing setup.

Well I am pretty sure I deleted all the tuners then set them all up when I installed the HDHomerun, but I am not about to blow them away and then have to setup my channels again to test. Let me know how it goes for you opel70.

Well, I just deleted all tuners, and added my two new tuners. I went through my whole reconfiguring my digital channels, and then I checked my lineup. All messed up. Does anyone know the inner workings of Myth enough to know how the sorting actually happens? What column is it sorting on, etc?

I found this from July: http://cvs.mythtv.org/trac/changeset/10392. Nothing else concrete turns up.

I'm assuming from the lack of responses to this thread that there are very few experiencing this issue. You might enter a bug report at mythtv.org to see if they can shake anything out of this...

Ok, I have now spent a few more hours deleting and re-adding. From what I can tell, Myth uses the "atsc_major_chan" and "atsc_minor_chan" to sort the program guide. However, QAM channels need to have those set to '0'. It seems that having even one channel with those set to '0' completely confuses the sorting algorithm.

The only workaround I have come up with is to change the sort method to sorting by channel name, and prepend the channel number to the name. I haven't done this yet, but the only thing I can think that would be an issue is the need to also pad each channel number with 0's as it would now be sorting text instead of numbers.

I may post something in the DTV forum as this must have come up with others who are mixing QAM and ATSC channels.
