Thanks, all, for your positive responses. Since I no longer receive TVGOS via DirecTV I had to write the document "blind", so I'm glad there aren't any glaring errors that anyone here has spotted.
Thanks in particular to jjeff, who gave me some good suggestions. Maybe I should PM you, jjeff, but I'll stick a little bit in here first.
To explain my situation -- I have a Panny EH55, from which I've gleaned all of my direct experience with TVGOS. This means I only really know about ANALOG TVGOS, because of the analog tuner, and about TVGOS Version 9, since that's what is in the EH55. I also have a Sony KDL-46HX800 HDTV, which has TVGOS that is not set up due to the lack of an OTA connection.
I wonder if in addition to VCRs you want to add DVDRs to your list of devices that use TVOGS, after all I'm guessing their might be more TVGOS DVDR users left than TVGOS VCR users.
I think my omission of "DVDR" devices is a terminology error on my part. With my Panny, I have thought of that box as a "DVR" for years. Not until I finally entered the HDTV world did I realize that "DVR" is now used to describe a device which does NOT have a DVD burner! I should change the document's list of TVGOS devices to include VCRs, DVDRs, and TVs, because AFAIK those new-fangled (sorry) "DVRs" don't include TVGOS.
Another thing you might want to consider adding would be a section on CECBs that convert the OTA digital TVGOS to analog TVGOS, for our legacy(analog tuner only) devices. I believe both the DTVPal and Artec(select models) will do the conversion but I have no personal experience with either.
I completely agree that something should be said about DTVPal-type devices. The reason I left them out is that I, because of my "excuses" above, have no direct experience with them. I should probably go back through the forum and reread everything about the experience with getting these devices to work (painful as it was).
Under TVGOS features you might also want to consider adding a note alongside point #2 Eight days......... saying something like (note select TVs only utilize 24hrs of listings, called TVGOS daily).
Sorry I'm not up to speed on this. I should go back and read the forum again, since I dimly recall reading about it a while back. Am I remembering correctly that TVGOS Version 10 is "TVGOS Daily"?
Anyway, thanks again for reading my stuff, and thanks to Trip for convincing me to write all this stuff down before I forget it.
