Others will have much more to add, regarding the creation of an AVCHD DVD (to be played through a BD, Blu-ray Disc, player), but for the i and p, they are"
i = Interlaced
p = Progressive
Then, regarding the blank media choices, if one is going to a DVD-9, Double Layer, I recommend Verbatim. For a DVD-5, Single Layer, I recommend Falcon Pro, Verbatim or Taiyo Yuden. I do not recommend Memorex, recent TDK or recent Ritek (they were once respected producers, but have adopted the Memorex business model - buy the cheapest media that day, re-name it and place the logo on the disc, and sell the cheapest media possible. I also do not recommend any "store brand" blank media.
As for DVD-RW, I use those ONLY as a medium to test my Projects. I never deliver on a DVD-RW, and those stay in-house, for testing ONLY.
Good luck, and others will be along, to help you with the AVCHD DVD's.
Thank you Bill,
I haven't yet received additional feedback, other than yours. In the meantime, would you be able to elaborate a bit more on when I should use the Interlaced versus Progressive please?
Sorry for my delay, but I spent the weekend booking our travel for 2014, bought a new car for my wife, and veg'ed out watching a bunch of TV.
For a breakdown of Interlaced vs Progressive, this article does a good job: http://www.dummies.com/how-to/content/interlaced-vs-progressive-scanning-methods.html
At the start, one would want to match their original camera footage to the Project's settings. Then, depending on the final delivery, considerations can be taken into account, when defining the output settings.
Good luck, and hope that article helps.
