I strongly doubt there was any Lionsgate release of THE CHOSEN in 2002, since VHS was pretty much a dead format by then. The Amazon listing you are likely referring to is from a collector vendor and not Amazon themselves, as such the information the vendor filled in can be disputed. Vestron put out THE CHOSEN on VHS in the '80's since at that time, they had a licensing deal with Orion, who did still own the film then; an Orion logo is clearly featured on the package. This release has no bearing on the Lionsgate DVD release, which is connected to their overall StudioCanal deal. The Embassy library split works like this: initially, MGM got video rights because Embassy Home Entertainment was part of the Polygram library they bought in 1999, but after a few years they relinquished any further control, so their full owner, StudioCanal, could shop them around; Anchor Bay initially took them, along with the EMI titles also in their library. As it stands now, whatever Embassy titles MGM put out on VHS or DVD they get to keep unless they give them up (for example, they continue to put out ESCAPE FROM NEW YORK, but gave up VICE SQUAD), and Lionsgate gets all the rest. A lot of IMDb credits should be taken with a grain of salt; I'm not 100% sold on any Embassy involvement in THE CHOSEN, since they would have gladly released it themselves in the States. I more likely think that StudioCanal inherited the title from the Amati family - other films they produced like CANNIBAL APOCALYPSE belong to StudioCanal, if not worldwide then in most European territories. So your hypothesies are generally correct - MGM's ownership expired - but the names and parties involved in bringing it to Canal+ and Lionsgate are slightly off.
