trekcore had some screencaps of Deep Space Nine on DVD. I have held off on buying the complete series because i was waiting for it in HD.
I guess i will be adding the DVD set next just out of a curiosity over the video quality. The BBC America Broadcast was horrible for the first two seasons, the DVD has to be better than that.
I no longer have my tapes but i taped each episode as it aired, and that was what the BBC broadcast looked like. Low quality resolution probably no more than 240 lines like a VHS tape.
Only recently have the prices come down on the blu ray sets for example that i could even remotely endeavor to collect them, or the complete DVD collections. Paramount has always inflated the prices for Star Trek going back to the old Columbia House days. I still have some of those tapes.
