I'd say that's about normal for maybe 20-40 hours of
recordings depending on the ratio of mpeg2 recordings to mpeg4.

For mpeg4 it will be 3600 records per hour, and 7200 for mpeg2 (for
the pvr-250 at least, not 100% sure about dvb).

Still, writing even every 7 seconds shouldn't slam your cpu that much
unless you're running with < 5-10% cpu free and low memory so it has
to hit the disk too much when it hits mysql.
