The laserdisc logo was one of the pre-defined avatars on the old board. I think both Laserman and MeBeJedi used it at one time or another.
Alek, thanks for your post, more laserdisc capture discussion is always welcome here. Looking forward to seeing some screenshots. Do you have any intention to capture any pre-THX discs at all (e.g. the Japanese Special Collection or US Special Widescreen Edition)?
