From 1998 onwards, Vanthilt became involved with the media in Belgium, mostly on Flemish radiostation Studio Brussel and TV-station Eén. On TV, he hosted various shows, such as quizzes ('Quix', 'ViaVia', 'De lage Landen'). His most famous quiz was perhaps 'Tien voor Taal', a language-centered quiz, which he co-hosted with Dutch presenter Anita Witzier. He had a short stint with vtm, for which he hosted 'Tilt' (1993–1995), but soon returned to the VRT. He further hosted reality show "Wit in Vegas" (2005), in which he accompanied couples wanting to get married in Las Vegas. On 26 November 2005, Vanthilt co-hosted the Junior Eurovision Song Conteset with Maureen Louys. In recent years, Vanthilt has appeared on screen as a talkshow host. From 2006 to 2009 he appeared as a weekly guest in late night talkshow "De laatste show". He continued on to host the summer talkshow "Zomer 2007" and "Zomer 2008", in alternation with Ben Crabbé. Since 2009 he has his own summer talkshow, "Villa Vanthilt". These shows are recorded in a makeshift studio in a Flemish city. In 2009, the cities chosen were Ghent and Hasselt; in 2010 Hasselt and Kortrijk. He has since started the 2011-season of Villa Vanthilt, five weeks in Dendermonde and five weeks in Roeselare. His program is scheduled to run to the end of August. Since 2009, Vanthilt also hosts "Ook getest op mensen", a TV show mainly focusing on health related consumer issues (Eén).
