There is always option of fast track via BKK airport. You can use it via visa agents, there should be no problem there. I also have DTV soft power and had no problem land cross, but I would consider fast track BKK in 180 days if DTV rulez get more stick or so.
I got approved DTV 17 Nov, crossed land border via Laos, no questions asked, 5 seconds. Luck I quess but I have heard Phuket is the toughest imigration control in TH.
