There probably is but we are going to need a few more details.
What is the Make and model of the DVR? What are the computer's specs (model, memory, hard drive space etc)?

Mickibob - please provide the information requested, plus whether the DVR is part of your cable package, the type of programming you are trying to transfer, and the reason(s) you want to put the DVR content onto your computer?
For myself, I have Time-Warner cable w/ their DVR (some features are disabled on the 'generic' device), so there may be limitations depending on your machine. For years, I've been recording old TCM movies in public domain and then burning them to DVD on a stand alone Sony DVD recorder (shown below) using just RCA connectors (i.e. one for video and 2 for sound) - I'm on my second Sony model which does dual layer DVD blank discs.
Two problems which you may have to confront: 1) I have to record to DVD in 'real time', so takes a while! and 2) I have no option to grab an AV file from the DVR (e.g. using a USB stick) to transfer to say a HD on a computer. If your DVR does not permit easy file transfer then the time factor might be an issue for you.
There should be no problem in hooking your DVR to your computer w/ some type of AV connection (e.g. HDMI if compatible) but you may have to deal w/ the issues above. Good luck - Dave
