One year later, I suppose, Renardo_11, you probably have an answer, but for learners following in our footsteps, I'll answer:
As a native American English speaker, I would comfortably use both start and begin with either infinitive or gerund to mean the same thing. I think Brian G was saying the same thing.
Of course, if I were a MOD, I would refuse to accept the gerund form in this sentence because the infinitive form is used in the Czech. (I would be a nasty, mean and unpleasant MOD.) Of course, if I were a MOD, I'd also be frequently passed out in a corner with an empty wine bottle - broken in spirit by the demands of 400k+ users, and by the hundreds of translation variations to keep track of.
Merry Christmas to all, and three cheers for the MODs. If I knew how to deliver it, I'd buy you all a case of wine.
