Bartle Frere, 50, from Shipton Gorge, Dorset, is accused of 25 sex offences, including the abuse of boys in the UK and India. He denies all the charges.
The court heard Mr Frere was arrested on 10 November 2013, at Heathrow when he returned to the UK from taking a BA flight to Bangkok.
Before landing in Thailand he had typed into search engines on his smartphone "Where do you pick up underage boys in Bangkok?", the court was told.
|The court heard police had taken videos from Mr Frere's home|
The six films featured naked Ukrainian boys, aged about 11 to 13, playing.
'Baths and cuddles'
The videos, which featured the boys in paddling pools and wrestling, had names such as Commando Christmas and Water Wiggles.
Another video was kept in a folder on Mr Frere's Mac, which Dorset Police's computer expert was unable to access, the court heard.
Simon Ray, defending, said the encryption software used was standard issue on Apple computers.
The court also heard how Mr Frere chatted to boys as young as 13 in India and would arrange to see them in hotels for "baths and cuddles" when his work took him there.

The mother of one said she became "anxious" about her son doing odd jobs for the defendant when he came home with his clothes washed and dried by Mr Frere.
She said she asked her teenage son if anything "weird" was going on, which he denied.
He is accused of five offences of arranging or facilitating the commission of a child sex offence, relating to boys in India.
He is also charged with five counts of indecent assault, one count of indecency with a child and two charges of serious sexual offences in relation to one of the boys from the UK.
With regard to the second UK boy, he is charged with one count of sexual activity with a child and one charge of attempting to record a person doing a private act.
The defendant also faces six charges of possessing indecent photographs of a child and four charges of making indecent photographs of a child.

In a video shown to the court, one of the alleged British victims, now in his 20s, said he engaged in sexual activity with Mr Frere about 10 to 15 times over a two to three-year period from about the age of 12.
He said it began at Mr Frere's house where he did odd jobs, including mowing the lawn and washing his car.
He said Mr Frere always offered him a bath and afterwards he would watch DVDs while wrapped in a towel.
The abuse began with Mr Frere rubbing his back and chest, he said.
The court heard, over the course of the alleged abuse, the boy was given money, fake designer clothes and a £250 pair of roller blades.
In the video, he said: "I would always get nice things. Sometimes I wouldn't have to work."
