I may be wrong, but Googling that model no. brings up eBay and other listings for camcorders masquerading as Sony, JVC and Canon but these companies do not appear to produce any models with that no. The camcorder may really be a Tec DV7000 -
here - (unless that name has been hijacked also!).
Read this from the JVC website (notice the MX prefix):
"JVC have been made aware of certain camcorders, digital still camera and DVD players being sold under the brand name "MXJVC" or "DVXJVC", and with these products are documents indicating that JVC is responsible for 'after sales service'.
These products are NOT genuine JVC's and have no connection whatsoever with JVC.
As far as JVC is aware, these products are sold in Spain and in the Canary Islands mainly to tourists. We have also noted that they are being advertised on some internet sites."
