A search on the JVC website (
www.jvc.co.uk ) returns NO information on a GR-DVX25 it doesn't exist on the JVC website, the only model featured on the JVC website is the GR-DX25 which only has DV-out.
As you say in the review of the Camcorder in Camcorder user it does say DV-in/out but in the specifications published at the back of the magazine it now says DV-out only. so they are not consistant in the one magazine.
Also in the magazine is an advert for
www.letsgodigital.co.uk where they are offering a GR-DVX25 but do not give a specification, however if you visit that website you get nothing if you search for DVX25 but can find a DX25 which is DV-out only.
It seems that somebody at JVC is doing their very best to throw confusion all around.
