The video, which has seen been taken down from YouTube, shows Jones addressing an audience on behalf of Fuso, who are linked to England sponsors Mitsubishi.
Jones and the Rugby Football Union issued apologies soon after the footage came to light, and the England coach started his pre-Ireland press conference with a brief statement.
Desperate to avoid a third successive defeat that would enable Ireland to celebrate a Six Nations grand slam at Twickenham Eddie Jones has named an England team showing 10 changes, including a new halfback pairing, for Saturday's finale.
When talking about his England record last summer, the 58-year-old Australian told the audience: 'We have played 23 Tests and have only lost once to the scummy Irish. Even if Eddie Jones's remarks about the nation in which Schmidt has invested nine years of his life were meant as a joke, no one found them particularly amusing. They've got a very distinct style of play and we feel those two are going to get us on the front foot.
"Iain has got a little bit of time under his belt. he has progressed a bit more".
'I'd just like to say I've apologised for the remarks, ' said Jones.
"Eddie has apologised for his inappropriate remarks, and the RFU is also very sorry for any offence caused and will apologise to the IRFU and WRU".
"I find it a bit boring, they are not a joy to behold", said Williams of the Irish team.
Jones made a decision to perform major surgery to his team following England's 22-16 loss to France in Paris last weekend - a defeat that ended their hopes of a third successive Six Nations title under the Australian coach.
Ireland, the outright tip for the Six Nations, justified faith in them by wrapping up the title with a game to spare.
