Re: Original or remastered effects?
Just a note: if you don't have a high definition TV, don't bother with Blu-Ray. This is especially true if you want to watch Star Trek or other "full screen" TV series. The picture will not fill the screen and be quite smaller, because the format is made to fit the 16:9 widescreen aspect ratio. Widescreen movies will always have the black bars and the top and bottom, which probably won't be an issue, but Star Trek is in 4:3 and it will have the black bars on the top and bottom as well as the side. It's in the same space as a widescreen movie, but inhabits only the center of the screen.
Rectify this by accessing your players set-up menu and changing the output settings to "4:3" TV and "480/576i" appropriate to your region.
