Yes, a multirec-capable tuner (which most DVB-x tuners are) does not
have this problem to the same extent, because they natively support the
concept of multiplexes which MythTV's multirec capability was designed
for. My HDHR DVB-C tuner, for example, also does not, in that it has
multiple virtual tuners available that can be swung into service for the
purpose of back-to-back recordings (or indeed for parallel recordings of
any combination of channels on the same multiplex).

But the encrypted channels my cable company provides need to be accessed
by means of a set-top box, and there is presently no "multirec"
capability for one-channel-at-a-time capture cards.
