Definately DVD. I have a few old VHS tapes, but they are replaced with their DVD counterparts
BR, well no, for the simple fact I have an old TV on which it wouldn't make a difference in image quality if I would use DVD or BR. Besides BR movies are still too expensive in my opinion.
Secondly I don't want to rebuy my entire movie collection into BR, to see it being replaced in 5 years with something new
I am (hopefully) going to pass on BR
