Officially… not as far as I know. Unofficially… yes, of course - they were quite popular for a time especially when cheap VCD imports were a thing (cheap and easy to do online from the Far East) for a while before the 2006 OT DVD release.
The likes of Nathan Butler, Video Collector and projectcclarke would likely know a lot more about these kind of releases than me - it may be worth asking them mate.
