As for what is allowed to be discussed in this forum, I'll try and keep it simple:
- A capture from VHS is preservation. You are allowed to discuss your project and its distribution.
- Enhancing a released DVD (by mixing alternative audio/video, converting PAL to NTSC or letterboxed to anamorphic) is a Custom DVD. You are allowed to discuss your project, but not its distribution.
- A straight copy of an out-of-print DVD is piracy. You are not allowed to discuss such activities here.
