Regarding the 720p REPACK, if it's an official release, there's no record of that. Typically, older films might be remastered and released in HD as part of a re-release or a special edition. However, if the 720p REPACK is a non-official version, it would likely be a fan-made version with the original film converted to a digital format suitable for streaming. This would involve re-encoding the video to a higher resolution, possibly improving compression, but maintaining the original content. It's important to differentiate between official and non-official sources here.
