Thanks for taking the time.

Especially for timeslot recordings this would be a great improvement because
it is rather unlikely that a show gets scheduled for the exact same time every
week or day or whatsoever. It usually tends to be around a specific time.

Does the programid of a specific program change if the EPG gets updated over
the air (e.g. start time changes)? If it does not, one could actually only use
the program start time for kSingleRecord and things would always be fine.

Unfortunately, MythTV has a tendency to favor the "lost/no recording" case
somehow. Tying a single recording to its EPG listing and letting it go if the
start time changes by a minute, makes not much sense. Actually following the
EPG for changes would make a lot more sense in this case.
Another example is ticket #6897: The device handler shouldn't give up easily
but keep on going like a normal PVR would do, so the user gets a corruption
but the rest will be fine. But that's a different story.
All I wanted to say is, we should _always_ favor a partial or even partially
corrupted recording over simply losing it totally. And naturally, we should
try hard to record what the user scheduled and not bother him/her until really
necessary like the show was replaced by something different on the EPG and we
have no way of knowing what to do next.
Stuart, are you planing on working on this or should I have a look at it if we
can settle on a single solution?
