Why does UPN Channel 44 come in (via antenna) on my television's
channel 100? What channel is WB Channel 20 supposed to be coming in
on? Are all these misalignments listed somewhere? I'm in the San
Francisco Bay Area of California. Thanks!

Sometimes the local cable company leaks some signal into the air, or
some other defective equipment nearby produces a signal on a different
channel. If the former, cable customers in your neighborhood get
channel 44 on cable channel 100.  Ask some of them. Some of them will
likely have a list that shows what they get on each cable channel.
 Some newer TVs may be different, but with most older ones, you select
either cable or ant. then click on auto program. You can't get channel
100 on ant with most TVs designed for sale in the USA. Was your TV
perhaps designed for use in some other country?
 The most likely explanation is: You think your TV is programed for
antenna, but it is actually programed for cable. If you get a good
picture on all the local channels on some channel, plus some extra
channels you are geting a free bonus. Why complain?
 If it is cable leakage, the cable company may be willing to make
repairs, even though you are not their customer, as leakage can get
them in trouble with the FCC = Federal Communications Commision. Call
customer service, tell them you think they are leaking signal in your
neigborhood, then answer their questions as best you can.  Neil

It's possible that you have selected CATV instead of UHF/VHF as the
input signal for your TV. Check the onscreen menu setup.

It's also possible that Channel 44 has a repeater to rebroadcast on
100 that you are picking up.

No I don't think my weird channels corresponded with local cable
channels, at least not those of the people I asked. So that part's
still a mystery.

However, I did finally get the time to check out whether my tv input
was programmed to cable instead of antenna. It wasn't easy, because
this Sylvania set uses very different terminology. But I went thru
every possible setting and when I came to "Channel set up: add/delete
ch (catv)", I figured I must be getting warm. I managed to change that
last part to (tv) and then I hit "auto-preset" and the channels all
righted themselves!! We no longer get the interesting foreign
stations, but that's ok.

So thanks for your encouragement and advice!
