No, I don't think they would, for several reasons.
First, you have to remember the whole concept of American commercial television is to make money -- and that money comes from American advertisers. Ratings are important not for their own sake, but rather of a measure of how many people are available to see any advertisements. Granted, in this day of recordings and remote controls this concept may be out-of-date, but there it is, nevertheless.
Foreign, pirated, VHS/DVD sales, etc. have no impact at all on how many people viewed the commercials that the sponsors aired during the program. Sponsors pay SciFi to insert their commercials in the hope that viewers will buy their products / shop in their stores. Further, the sponsors are promised a certain number of viewers.
People who don't view during the original airing can not be counted as people who watched the commercials. Therefore, as far as the people paying the bills are concerned, they don't count.
Now, maybe somewhere, people may be wondering about how well this show might do in other countries, or on VHS / DVD. However, since SciFi does not own the rights to broadcast this show in those places or formats (at least I don't think so), they don't care.
