I have some questions for those who have purchased the home media of TFP season 1. I want to obtain the set, but none of the stores I've visited so far has the blu-ray version, they all have only the DVDs. I know a few internet sources to acquire the blu-ray version, but I'm not sure if it's worth going through the trouble. That maybe I should just buy a DVD set from the stores with half the price. Are the qualities, both visual and audio of the blu-ray much better than that of DVDs? Do they have some bonus features the DVDs don't? And do they have subtitles?
