The V+ HD service isn't being withdrawn overall any time soon. The older V+ HD boxes (made by Scientfic Atlanta) are currently being swapped as next year the HD channels will move to a format not supported by the older V+ HD boxes.

In regards to saving content you can do so to a VCR or DVD Recorder. See this help article:
