I'm not sure if Locks will remove the extraneous (to you) movies but you could try. For HD, choose either 9417 and higher channels numbers or the better organized map-down channels below 500, not both. With locked channels from the wrong set you may be asked your PIN often. I've done that and they may appear in the lists with PIN required to see their title. Annoying.
I usually use the HD-only guide for most recordings 387 down to 300 5 pages of 7 lines. I supplement with 139 to 122 HD/SD to pick most of the rest of the movies--one page and skip right 3 hours. I don't watch Lifetime or even USA much. You do use the 3-hour guide and not the 1.5 hour one?
You may have more luck with Dish Remote Access web pages. You can select by types (Westerns, musicals, etc.) or channels and look out now, this day, or this 8 day. The ratings a tad lower generally, i.e. they are not the Tribune ones, say 1/3 star lower or less on average. This also allows you to set them directly into your recorder.
Be warned the recorder by Satellite will only define up to 96 titles and some number 250 to 400 of future recording events. The DRA will allow more recordings to be set but then you cannot set any manually until you are below 96. It helps to have Ethernet for it to "see" what you have. The DRA can know multiple recorders but you can only set one at a time.
