Well, went back to 5020 after finding a new glitch in the channel list. While it always has been a bit quirky when re-naming channels (if you re-scan the satellite even 1 minute later it reverts to its original name), now when you re-name a channel it does several extra unwanted things. First off, after renaming one channel with a spelling mistake, I went back and re-did it. It would take only until I exited the page or scrolled up the channel list, and then the spelling mistake re-name would reappear. Several edits produced the same glitch. As well, if you highlighted the newly re-named channel in the list, the usual satellite/transponder information line at the bottom was no longer there for any channel renamed with 5209 (previous re-named channels were OK). Further, when on a newly re-named channel, when I went to the channel list, it showed it from the beginning of the list, not from where the channel was. One more thing I noticed (before I gave up on 5209) was that you couldn't delete the re-named channel from the Favourites list, it would disappear when first deleted, but if you scrolled up the list and then back down, it would re-appear!
Went back to 5020, re-named the channels, deleted the unwanted channel from the Favourites list, no problems whatsoever (unless I re-scan!).
