So, for example, if you wanted to tune 3-10, and if the digit 8 was never used, then you would reprogram your RTV's IR Blaster code so that digit 8 sent the subschannel separator (dash or period) and then remap that to channel 3810 to send 3-10 specifically.
The thing is, right now, pre-WJLP, I did not NEED the subchannel separator. Now, I am just not sure. I came up with the hash swap idea some years ago, for use on a box that absolutely required it to tune any subchannel. The CM-7000 did not require it, which was one of the reason I purchaed them six years ago (Wow! Six years...)
You should play with your remote and the CM and see what you can do to tune subchannels without using the subchannel separator key. I don't think that changing the number of digits will impact that.
With the CM-7000, sending a leading zero DOES make a difference.
WCBS-DT and WLIW-DT are two OTA Stations receivable in my market. WCBS-DT broadcasts with a PSIP of 2-1 and 2-2. WLIW-DT broadcasts with a PSIP of 21-1, 21-2, and 21-3.
If I send 2,1,enter to my CM, it will tune to 21-1.
If I send 0,2,1,enter to my CM, it will tune 2-1.
It understands that a leading zero means a primary channel less than 10, and all other digits will be considered part of the subchannel. The only question is, would it understand 0,3,1,0, enter and tune to 3-10? And if that is successful (remember, I sent 4 digits, and would have created the custom remap file to have WJLP on 310 for this effort), what would my CM tune if I sent it 0,2,1,1,enter (to tune WLIW-DT 21-1). I think it would try to tune 02-smething, and fail.
I don't think that just because you send four digits, that makes the CM think that there are two digits of subchannel. I don't think that it "right justifies" what you send, or that it starts from the left and pushes the digits over from the channel to the subchannel. From everything I've read, they work fine with one-digit subchannels, but there is an ambiguity, as you already found, with two digit subchannels, and I think the CM still tunes using the same method. That is, I'm not sure that you can auto-tune a two digit subchannel without using the subchannel separator key.
But, you should play with it and see. Although, even if you can get four digits to tune two digits of subchannel, then you'l have to work on your one digit subchannel mappings. I think that your example of tuning 11-2 would mean that you remap that to 1102 to make four digits, and that would tune 11-02, which should work properly. Of course, then the RTV will remap channel 1102 to some less-than-four-digits channel, but it will still tune to channel 1102, which might make the CM happy.
If that works, then all the problems go away, and all I would need to do is modify the remap file and send 4 digits....
I would need to make my remap file read something like this:
WCBS-DT 2-1 201
WJLP-DT 3-10 310
WNBC-DT 4-1 401
WNYW-DT 5-1 501
movies! 5-2 502
WPIX-DT 11-1 1101
AntennaTV 11-2 1102
ThisTV 11-3 11-3
I just don't think that the auto subchannel tuning works with two-digit subchannels, but if you can make it work with the remote, then you should be able to get it to work with the ReplayTV. Try tuning channels 0310 and 1102 from the remote and see what happens. I hope that works for you, but I don't think that going to four digits is going to do what you want, I'm just not sure.
Agreed. I was just hoping someone else was experiencing a similar problem. I won't be home until Thanksgiving, so this will have to wait. I just needed a distraction, so I decided to post....
