My brother asked me for a little advice on the different type of DVD formats and I figure this forum is the best place to start as my knowledge is pretty weak in that area. Really looking for two answers/types of info: 1) Can anybody point me (and him) to a good resource that describes the differences in the burnable formats (ie: DVD +R, DVD RW, etc.). Between the two of us we're fairly fluent in both home theater and computers, but any additional commentary that one would provide would be appreciated. 2) He's planing on getting the burner to use with his computer (primarily to burn DVD's of home movies and other content) and not a standalone burner/DVD player. What concerns should he have with the compatibility of these computer burned DVD's to play in a variety of DVD players. In other words, if he edits and burns a DVD of his kid's Birthday it needs to be able to play in: A) his player (sony); b) his in-laws' player (JVC); c) his parents' player (pioneer) and so on. This may be linked to the above question about formats, but I am also looking to understand the other issues that may create problems, especially when dealing with older (2-3 years) DVD players that may be sitting in peoples' homes. Thanks in advance.
