That sounds reasonable. Are you sharing the cache or just
making sure the channel scaned on each backend don't overlap?
Also, does this scan all the sources with independent tuners
at the same time, or just one source at a time?

Which sounds very reasonable. Lets see if it ever grows to
unreasonable size in a week or two of continuous use before
we start trying to 'solve' the memory usage problem, which
may not even exist anymore.

Ah, ok. I was thinking this could also fix the 'unknown'
program when you tune to a channel that doesn't have
program data yet, but using the existing overrecord
functionality sounds reasonable.
