I am extremely new to this. I recently downloaded an rmdu file that coincides with my TV. is there any way to import that to my mx 3000 software? any help on this would be amazing!!! thanx

my tv is a 32" vizio

If you mean rmdu files from the JP1 site, you can't directly import that to the MX3000 software, but you can use the info in the file to create codes you can import to your software. You need to open it with Remotemaster (http://controlremote.sourceforge.net/). With RM, you will be able to see what protocol the device is using and the command numbers (called OBC in RM) for all the functions. You can then use the info to generate Pronto Hex codes for each of the functions using makehex (http://www.remotecentral.com/cgi-bin/files/rcfiles.cgi?area=pronto&db=other&br=utilities&dv=irprograms&md=makehex&kw=makehex&st=&ar=&dt=&so=&pg=1&file=utilities/makehex.zip).
