I agree that bitrate isn't the issue. There's a point, however, when
you could hit an unacceptable I/O wait level due to all the seeking
required when writing to alternate files (one file per recording) if
using a single disk. That point may still be some huge number of
recordings, so--as you mentioned--various data points from various users
performing tests would be worthwhile. When reporting info, it's
important to mention the number of disks in use, whether root and/or
mythtv and/or the MySQL DB are on the same disks and/or partitions, and
probably more configuration information that I didn't think of...
