There are a variety of software packages that promise to enlarge digital photos with reduced artifacting. I haven't used any of them myself, but certainly before purchasing anything I would do some web research to see what the competing products are, whether they have demo versions, what kind of user endorsements they may have garnered, etc.
Also, the newer versions of Photoshop have a new option under 'Resample" in the 'Image Size' dialog, listed as 'Best for Enlargements'. You might get satisfactory results in Photoshop with the right settings, without resorting to other software.
12" isn't that big. We made a lobby sized poster for a film by blowing up a 720P video frame, and it worked fine for the purpose. As I recall, I was looking into those enlarging software programs but we hit a deadline, and just used Photoshop. Getting rid of scanlines is probably a matter of applying a suitable plug-in filter as a separate process from resizing. I remember that we got the poster from Kinkos, but I don't remember if we gave them an enlarged file, or something with the text in vector graphics and the photo at native resolution. Kinkos makes digital enlargements all the time, so you could call them and ask them how they do it. They might be able to make a nice 12" print of the video frame for you for less than your time hassling with it yourself is worth.
That said, I'd still like to hear what anyone has to say about any of those enlarging programs...
