I will use this thread to explain some more on it.
Remember I talked about the "parent" of your custom views? Here is what I meant:
In Theater View, you have Audio, Image, Video, etc. Under video, you have Movies, Shows, and Guide. And under Guide, you have various ways of showing parts of guide entries:
Video/Guide/Guide
Video/Guide/Favorite
Video/Guide/To Be Recorded
Video/Guide/Search
etc.
In your case, you have
Video/Guide/Client Guide
Video/Guide/Server Guide
etc.
The bold face part is what I meant by "parent" (the second portion).
Your custom rules (OTA, Favorite, etc.) are rules for the third portion of those paths. The default rules for the second portion (Guide) are the following:
Custom: [TVTime]=>#TVGuideStartDate
Custom: -[=TVInfo(ChannelKeywords)&DataType=[list]]=[Hidden]
Custom: [=TVInfo(IsOnNonTopGroupedChannel)]=[0]
and one modification: Database location: Television Guide.
The combined expression looks like this:
[TVTime]=>#TVGuideStartDate -[=TVInfo(ChannelKeywords)&DataType=[List]]=[Hidden] [=TVInfo(IsOnNonTopGroupedChannel)]=[0] ~d=g
In build 62, MC will automatically replace that expression with this one
"[TVTime]=>#TVGuideStartDate ~d=g"
to gain efficiency. So you do not even need to do anything to enjoy the new efficiency. However, if you modified those rules manually, by adding something extra, or by changing the order of the default rules, then MC will not be able to identify that string, and therefore will not run faster. In that case, you can manually remove the two rules that are meant to be removed.
