Super TV Tuner w/FM

Has anyone bought this item off ebay?It is an advertised super tv tuner w/FM.There is no manufactor name or support website anywhere on package.It does have a driver disc with it, however from the time you restart windows with card installed to try and install software you keep experience software is not digitally signed for windows alerts and repeating crash after crash.I was forced to uninstall card and use system restore to make computer operate again.Has any of you been through this nightmare and what did you do???JO.
