In contrast to what you stated, insofar as the missing/incomplete descriptions are concerned, I have been able to improve upon this by
re-scanning the channels (to force a guide update).
The timing of this is important. It appears as if they may be updating the listings only once a day. If you re-scan prior to this time, the data remains the same. However, if you re-scan beyond that point, it will fill in (at least some) missing or incomplete descriptions.
I've found (from my experience with this) that a safe time would be after 6:00 PM (east coast time).
Having a quick guide update option incorporated into the menu would save considerable (and sometimes wasted) time with this process!
Well, I certainly didn't have to wait 30 minutes! My guide "normalized" after 5-10 minutes. But it does seem like, if there's any chance of some problem happening, you're the one it will happen to. Maybe you should change your handle to "Murphy"
My experience has been that Rovi starts with a "default" guide that has no or generic descriptions and a lot of mistakes, then updates it with corrected and more detailed info weekly. Often I don't see info for a Mon.-Fri. show get corrected until Sunday, or even Monday - but once it does get fixed, it's fixed at least for the rest of week 1. (Week 2 is often less reliable, although some networks are better than others.)
So for me, forcing a download on Sunday, then refreshing my timers, might be of some benefit, but not so much the rest of the week. YMMV.
I agree there should be a menu option to download the guide without having to resort to kludges like changing the Zip code, rescanning channels, or doing a cold boot (another method that works, BTW). WMC has an option like that; I don't use it often but it does come in handy on occasion.
BTW, CM/E* could steal another WMC idea: let you set the time of day the guides are auto-downloaded. I have my WMC set to run after 6:30 PM Central time, as M$ seems to update their servers usually around 6 PM Central (4 PM Pacific).
Also, I think the whole Zip code idea is outdated. It started with TVGoS, where each TVGoS station in a market (typically the CBS affiliate) would broadcast guide info not only for stations in its own market but also for nearby stations in surrounding markets. TVGoS devices needed a Zip code to determine which market's guide to use.
But now that it's all on-line, it would make more sense to just upload all the stations' TSIDs from the DVR+ to Rovi and let Rovi send back the correct guides for whichever stations the DVR+ actually receives.
