This also guarantees that you can still pull guide data even if the cable company is doing ADS or is digital-only. (You can pull the data OTA, then use those guide listings for the cable input.)
OK, an update on this issue for those who are interested.
sderby's statement above is true at least for Panasonic DVD recorders that use the TVGOS EPG. I have run a little test on the difference between downloading EPG data using an OTA connection versus a direct analog RF cable connection.
I receive my cable service in the Philly area from Comcast and although I subscribe to digital service, I have the analog RF connected directly to my Panasonic E-500 and E-65 DVD recorders. Although many here have stated that they receive their EPG data (host channel) from a non-commercial PBS station, I have two
commercial TVGOS host channels, the ABC station (WPVI) and CBS station (KYW) in town. This was established by identifying the host channel on the diagnostics screen. The actual host channel used by the EPG alternates between the ABC and CBS stations. The channel list downloaded by the EPG lists all the analog channels as well as digital channels available on my Comcast cable service, and some channels (mainly New York City channels) that I do not receive. So in this case, sderby is correct, although I have the TVGOS EPG setup with no cable box, the digital channels are included in the download.
I decided to test whether the TVGOS EPG behaves the same if the signal was received OTA. So I disconnected my E-65 from the cable, connected a rabbit ears, and reset the TVGOS EPG to OTA (no cable). I did a reset, and so the clock showed a flashing 12:00 indicating that I had reset the TVGOS. Within 10 min, the clock was reset to the correct time.
After 48 hrs, I decided to check the TVGOS. What I discovered was very surprising. I expected the EPG to download only the OTA channels in the Philly area. What I found was that all the OTA channels in Philly and
New York City were listed as well as some from other Pennsylvania cities such as Lancaster. This was surprising because without some sort of super antenna with an amplifier, the stations in NYC (90 miles away) cannot be received from my location. However, what sderby states is true, many cable channels were listed
. I did not count them, but it appears that all the analog channels were there as well as some digital channels. According to the diagnostic screen, the host channel was KYW (OTA channel 3).
Therefore, at least on the Panasonic models, you can use TVGOS EPG downloaded OTA as a substitute for the EPG downloaded via cable. It will continue to download the EPG if the cable service temporarily goes down. However, in order to use the EPG to record analog cable channels, you must have it connected to the analog RF cable input.
