MythTV will schedule both shows as desired, ignoring global
pre/post-buffering and respecting per-recording pre/post-buffering.
That is, if you have 2 consecutive shows back to back, it is likely they
will be recorded on the same card assuming they have no per-recording
pre/post-buffering. If you add per-recording pre/post-puffering, they
will be recorded on different tuners as tuners are available because the
per-recording buffers are absolute and non-optional.
