This is how I schedule all of my recordings, I only have to use mythtv's schedule bits to change from tuner 1 to tuner 2 or 3. Otherwise it is set up all through mythweb. I like having the ability of assigning cover arts to the recording schedule, so when they show up in the lmce video menu, they already have the appropriate cover art for the particular series. This cover art I obtain from the site
http://thetvdb.comSo I have not seen this issue, and again, I use this interface almost always to schedule my recordings.
Here is a question, are you using it on a different machine, like I use my laptop, I have only done it like twice from an MD or from the core.
Hope you get it sorted.

Seth
