First, the easy: artwire suggested leaving the 537 tuner on 7.1 and then program it to record 7.1 a little later. He's right - with this method I can record the digital 7.1
Before I did any channel rescans since the last time I posted, I discovered, on the 537 - when changing "up" digital channels, the 24's are skipped over because 24.1 has nothing on it. However, when I enter 24.2, digital MTV is there, and likewise when I enter 24.3, digital USA is there, and so on for a few more 24's including digital Discovery which is next. So I can go to one of the channels by entering the numbers, but I can't go up or down to get the others. I have to plug in the numbers. Weird.
Even weirder is that I found for analog channels, suddenly (at least I thought it was ok previously) I can't get above analog channel 8 unless entered the digit(s). Going up would just wrap around (I now forget what going down did).
I played around a lot and went back and forth from digital to analog and was not having the occurrence of static for analog anymore.
Next I was going to do Ken.F's custom channel rescan suggestion. I see I didn't do it completely right but here's what I did: I scanned all channels with the coax off (I had earlier switched over to a cheapo thin coax that pulls on and off instead of screwing). So I wiped ALL the channels and then did another scan with the cable on but I pulled it exactly when it got to digital 1 and pushed in back on as soon as I saw digital 8. When it finished - it leaves itself in the channel setting mode which normally you would just exit it at that point. But I immediately when into manual channel set and there was channel 2.1, in its fully color glory, in the background and the channel setting box showed it was already added. So I channel up to 4 which is also seen in the background and it was already showing as added. Likewise for the rest when I scanned through them - 5, 6, 7, 8, ... So I exit and all the channels are there just as if I didn't pull the coax for 1 thru 8! And both channel 7.0 and 7.1 are likewise present, and with the same exact problem.
But here's the weirdest of the weird (if that wasn't weird enough): Starting from 2.1, I go up channels, 4.1, 4.2, I go through the three channel KTLA 5's (5.1, 5.2, 5.3 - the last two are "KTLA This") and hit a couple 6's (KCET and probably DW/international), with a blank channel or two in between (eventually the blank went away on their own), and then, still going up, the channel 5's appear again, and still going up, the channel 6's appear again, and finally 7. I went back down and the order was likewise strange (I don't know if it was exactly the same). I went all the way down probably to 2 and then back up - and again the 5's came again after the 6's and then the 6's again before arriving at the (sic) 7's.
But, .... after going up and down through 5, 6, 5, 6, twice each, it stopped doing it. Went back to normal ... 4, 5, 6, 7, 8. Yep.
Previously the 537 was picking up a radio station on 6.1, but after this latest rescan it's gone. I didn't want it. Now my TV also has great trouble with the digital channels that Cox is sending over 6 (which seems to change once or twice a year). My very good quality Samsung LED TV (I came back to insert this in parens - I may be getting confused as it may be my 515 tuner I'm thinking of although the TV tuner has its own annoying quirks because of the difficult channel feed from Cox) at times gets multiple (different) channels with the same number and goes back and forth - made up example: 6-1, 6-2, 6-1, 6-2, 6-20, 6-2 (definitely not that but you get the idea). The TV used to get a whole lot of digital channels on 6 but lately it's only been getting about 4 or 5 and I have have all but two deleted on the TV's tuner right now. The two I kept for the TV are the two that I think the only two the 537 is now receiving (KCET - and maybe the other is that DW channel). Wow - lucky - no just weeeeeeird.
Now the 537 does not pick up 18.1 which it did before (was probably some garbage anyway) but it goes right to 24.2 (up from 13.1 maybe), and then to 24.3, and so on. No longer is the blank 24.1 there and I can move "up" channels to and through the 24's (one at a time) which I couldn' t do before. This is working right now!
I go back to the lower channels and moving up from the digital 5's, the tuner went directly to 8! No 6 & 7! I went down from 8 and it went to 5! But finally, 6 and 7 came back and things went back to "normal" - ha ha ha ha.
I went into manual channel set and deleted channel 7. Exited and went back in and added 7 back. Except that it can't be re-added. I'm now assuming that you can't re-add digital channels manually after deleting them? Is this true? At least I can't on this 537. Initially, I thought you could because days ago I deleted digital 7 and I had thought I re-added it. But maybe I didn't and that's why, after deleting the analog 7 ( at wajo's suggestion) that digital 7 was just blank - maybe it was already gone - at the time I thought it wasn't though. Anyway, I can't delete and manually re-add digital channels on this 537 so hopefully (I guess) that's the way it works.
I switched back to analog and the static problem came back -- it hadn't happened in a good while - I think it wanted to say hi. Going back and forth digital - analog doesn't get analog back to normal. Only power off does.
I will be returning this 537. I want the Mag for sure but I probably won't get another 537 because of this witch. I somewhat expect the channel 7 problem with any other Mag now (with whatever garbage Cox is sending as I think it is) but maybe not. At least I'm fully conditioned for that one problem.
Thanks and truly sorry to anyone who read this.
