It is a Venturer STS22AAS-10 bought from a well-known Supermarket. Standalone for the TV. I have a DVD/CDRW fitted in my computer. I have a friend in the USA who could (in the future) send or bring with him when he visits me US DVDs. I haven't exactly opened the box yet so if this model can't be changed I can take it back. It was the salesman who said he thought it could be changed. I am checking the links given. Thanks all.
Be warned some region 1 DVDs have RCE or "Regional Coding Enhancement" and may not work in a player set to multi region, it has to be set to region 1. Now with a software hack this is a pain, but not impossible to overcome. Of my last 3 US sourced DVDs 2 need the player reset to be viewed.
