Can someone explain to me how to use these Disks with either Burning Rom or Recode (they are RiData DVD-R DL) but according to Nero they are ML disks. apparently you can change some setting from DVD to ML but I’m not sure how, if anyone could clear the situation that would be great
The only DL media consistently recommended is Verbatim and you are likely to be asking for headaches with the media you have. Additional problems with the RiData might be time before the disks degrade.
If I understand you question, you want Nero to recognize you are using DL media. Depending on the Nero program, you are likely to have a pull down menu as shown in the attachment. Select DVD5 for SL and DVD9 for DL.
