What is the JVC receiver RX-8030VBK code for comcast DVR remote?

Found my answer by looking at some other sites.

Some suggested using a 1 before the number (new version of remote).

So I tried 10074 - didn't work.

Another site said that a 3 before the 4 number code worked better.

So I tried 30074 (0074 for JVC in comcast document) and it works great now.
