I would find this very useful also (on my personal wish-list).
My way of thinking for this was a little different to your approach, though
however it's done if it works I'll be happy :)
I prefer option 2 of your options, but I'll throw this out there anyway:
I was thinking of having the scheduler collapse recordings on a single
channel into a 'meta-recording'. For the example someone else gave, the
scheduler would have found:
8:30-10:45 Stargate Atlantis (Channel 7)
10:30-12:30 Puppet Masters (Channel 7)
And it would schedule a recording into a single file for 8:30-12:30 on
Channel 7. However the database would have two entries for the same file and
an initial cutlist which sets "Stargate Atlantis" to 0:00:00-2:45:00 in the
file (time offset) and "Puppet Masters" to 2:00:00-4:00:00 in the file.
This would affect commercial skipping, though the commercial skip would only
need to be done once I believe the cutlist in each virtual recording would
block it? This would have to be modified.
Deletions would need to use a 'reference count' mechanism (use a SQL query
for the number of rows which match the filename) and only physically delete
when the last reference is removed. You might add the possibility of
removing chunks from the file when they stop being needed by a recording
