You don't have to worry about 2GB seamless splits because you'd have to record for like 5 hours to even get to that point.
According to the manual, it's a (possibly audible) 2-hour split, not a 2 GB split.
OFOTD, just to get the facts straight, 2GB equals 2h54m recorded in 16/44.1, not five hours.
Humbugu, you're right, thanks for pointing it out!

This makes the recorder less useful, until it has been proven that the split is seamless. Anyway, with the competition in the marketplace, there's little reason going for the Kenwood when 24bit R09-HR is selling for peanuts.
