I choose the downloadable DVD version for one reason: Free shipping! Well that and with a broadband connection it gets to me faster (even with a fairly slow speed, understandable for files of that size that are probably being downloaded by a number of people at once-it still took about half a day to get the thing). Interestingly, however, I just today got a physical copy of it in the mail. I wonder if this has anything to do with complaints from people about not having compatible burners and/or discs. I do suppose that when you account for the price of a DL DVD it DOES about even out to what you'd pay for shipping.
Anyway, no complaints about getting a physical copy in the mail-I was a little disappointed that the download didn't include printable artwork for the case and disc anyway-btw as a note to Rifftrax you should consider including that if you plan on making any other downloadable DVD releases in the future. However, considering it seems that enough people complained to warrant sending out physical discs free of charge-I somehow doubt this idea has much of a future to it. lol
I'm curious in any case if my theory is true or if I just ended up getting a physical copy as well through some kind of mistake. Either way, I'm definately not complaining. As far as I know I don't have any working Dual-Layer DVDs on me right now (just a stack of 50 or so apparently defective Memorex DL DVD-Rs that I bought so long ago I doubt I can return them for a refund at this point) so now I have a physical copy I can watch without having to mount the iso file to a virtual drive.
