Can DTV holders obtain a 5 year Thai driver's license or only a 2 year license?

5 year drivers licenses on a DTV - experiences? I'm wondering if those who've applied for a 5 year Thai driver or motorcycle license (or both at the same time) as a renewal from an existing 5 year one that is expiring OR a 2 year one that should be eligible for an upgrade to a 5 year one, did you get a 5 year license or only a 2 year one?

I know Sefton Hanley got a 5 year license in Chiang Mai while on a DTV.

However, in Pattaya and Rayong, they're only handing out 2 year licenses to DTV holders when they go in for their renewals.

Any experiences from other offices?

I have the feeling Bangkok will renew for 5 years, but this is just a hunch.
