Programs in EPG data that are not in the M3U

Channels DVR Server
#1

I've been playing around with decoding the XMLTV EPG data from both Channels DVR and FastChannels in PowerShell. I noticed an anomaly with the per-source guide data from Channels. It will include some programs that are on channels that are not included in the corresponding M3U. The cases I have noticed seem to involve the "Gracenote" sources from FastChannels, but I suspect it is a problem with Channels, not with FastChannels. The programs that should not be included are from other FastChannels sources/feeds (choose your own terminology).

A specific example in my case, is I find these unexpected programs in my "FastChannels Entertainment Gracenote" source. The corresponding "FastChannels Entertainment" source is clean. I get similar results for all of my FastChannels source pairs. The non-Gracenote sources are clean. The Gracenote sources include the unexpected programs.

It's entirely possible I'm misinterpreting something or have a bug in my PowerShell code.

Try deleting and rebuilding the guide data in Channels.
If a channel changes from non-gracenote to gracenote, or vice-versa, the old epg will still be in the channels database.

That did clear it up.

Seems like Channels may have some difficulty dealing with the velocity of lineup changes generated by FastChannels. I'm fairly certain I did a full guide database rebuild the last time I added any sources a week or so ago.

I've been doing my own playing with m3u's but without any fastchannels. I have concluded we need/(could definately use) a way to tell channels how many days of guide data to grab.
the days of industry standard 2 week guide data doesn't work well in the streaming age.

classic cable would index of a couple hundred channels x 24hr (or 48-1/2hr) x 14 days and was manageble.
now with many sources x many hundreds of channels x non-classic hourly programming x 14 days quickly grows out of hand even with modern processors.

i want to setup camera feed recordings, but 15min placeholders x 2 weeks is way to much for info that never changes. I'd like to only have a day or two of those sources.

I know they did just recently make some changes on guide data caching and it is an improvement as far as I can tell, but it also has added bugs.
