In message #5931 I said I'll mention the configuration in another message soon.
When configuring my Panasonic to see the DTVPal as a "Dish Network Systems" brand of DirecTV satellite receiver the channel numbering was a problem. That is until I looked in the manual of the DTVPal and found you have to pad the channel numbers with leading zeros so that the Pal always receives 4 digits numbers.
5.1 -> 0051
11.3 -> 0113
(update: you can see some more info about setting these channel numbers in the channel editor in message number #5957 at

About sorting channels in the channel editor:
press submenu, keep pressing down arrow until the "more" on the bottom disappears, and then choose "re-sort numerically".
I adopted a practice of giving channels that had been turned on which I don't care about the number 999. And giving channels I might want to try in the future the number 998. That way I have less paging down to do.
(If the channel was already "ON" and set to "Air" you'll have to switch it to "Cable Box" or "DirectTV" before you can give a number of 999. But that's not enough. In the menu on the left you'll also have to switch "input active" to "yes")
(I seem to recall you might have to go into the submenu twice. The first time to assign the 999 number. The second time to set the "input active" part for the entry with the 999 number. The first time the "input active" field is grayed out.)
Speaking of paging up and down. The channel up and down button causes the listing to scroll in pages instead of individaul entries. I suppose this might not be obvious. I don't remember how I learned it. Maybe one of the TV Guide screens says it.
From hearing other people talk it seems that many might not be aware you should be able to add your subchannels besides just .1 to your channel listings. All you have to do is find the "call sign letters".

Here's an example of the information I've assembled from there:
dtvpal in non-tvg mode (alpha sort, only not enabled by default are listed):
kcsmd2 dtv 602
kqed air 9
kqed dtv 91
kqedk dtv 544
kqedl dtv 92
kqedw dtv 93
krcb dtv 221
krcb-dt2 dtv 222
kteh2 dtv 542
ktehl dtv 543
v-me dtv 545
dtv is short for DirecTV in the above. One kqed is enabled already. I need to turn on an additional one for my analog TV Guide listings. And for some reason I keep both in this list.

dtvpal in tvg mode (alpha sort, only not enabled by default are listed):
kcsmd2 cb 702
kqed air 9
kqed cb 191
kqedk cb 644
kqedl cb 192
kqedw cb 193
krcb cb 321
krcb-dt2 cb 322
kteh2 cb 642
ktehl cb 643
v-me cb 645
cb is short for Cable Box in the above.
With these lists it makes it much easier to know which channels I need to add. (My lists above aren't complete. There are other non .1 subchannels listed. I restricted it to the PBS channels to make them shorter).
The reason I keep the lists in an alphabetic sort order is because when paging down through the hundreds of entries in the channel editor it makes looking for them easier. Since the many turned off channels are sorted alphabetically.
When I first undertook enabling these subchannels I went through the effort to move them up in the channel editor. So that they wouldn't be hundreds and hundreds of entries away from the other enabled channels. I don't bother anymore. I just re-sort the list numerically as mentioned above. Entries that have an assigned channel number will automatically be moved to the top of the list.
Unfortunately I don't think there is a way to unassign a channel number for a particular entry once it has been assigned. That's why I assign the entries I don't care about the number 999. I do this even though I have the channel turned off.
I found assigning the 999 number to the entries I don't care about should be done before doing the numeric re-sort. Otherwise those channels get intermixed with the channels I care about. I suppose it isn't an absolute necessity though. So you have a cluttered Channel Editor view? Big deal. It is to me.

While I did this manually, I think this is definately something a programmable remote control that has macro capability would be useful for.
I would assign 999 [down arrow] to a button.
I would assign [enter] [enter] [down arrow] to another button.
Then after cursoring to the channel number column of the first entry I want to get rid of in the channel editor I would start repeatedly pressing the first of those two macro buttons. And then repeat the process for the ON/Auto/OFF column using the second macro button.
