Exclude Web-DL 1080p AAC2.0

Can someone direct me to how I can setup my HD downloads to be like:

[Top is highest quality first]

1-Bluray 1080p (usually is already DTS/DD5.1 audio)
2-Bluray 720p (usually is already DTS/DD5.1 audio)
3-WebRip/Web-DL 1080p but DD5.1 (but downt download/exclude aac2.0)
4-WebRip/Web-DL 720p but DD5.1 (but down download/exclude aac2.0)
5-HD-TV (usually is already DTS/DD5.1 audio)

I see in the settings to click on the ones you want but not sure where I put the options to exclude audio if its 2.0 web-dl. Sometimes I will have a HD-TV files thats overwritten by a WebDL 1080p but the audio is only 2.0 - in this case I would rather keep the HDTV version and not the web rip. Would this be handled under the “Settings” area under subtab “Indexers” then put something like aac2 in the restrictions area? Can anyone help me please?

Yes, exactly.

I been thinking about this more and now think I would get stuck with another issue being that if there really wasnt ever a release in DD5.1 for an old TV show but they had a 1080P Webrip thats maybe better quality than a DVD I would miss the file. Thoughts how I could setup a way always automatically capture the BEST quality sound and video?

You could enforce the rules based on series, older series could be given less restrictive downloads.

There really isn’t a magic bullet here, at least currently, preferred words would help, but we haven’t decided how those are going to play into the upgrade process (whether a new release would overwrite an existing release based on it containing a preferred word, when the original didn’t).
