umm ovredcoat you can't force a software dowload because it's controlled by the engineers of DIRECTV...
Thats not totally correct. You can force the NR at just about anytime. Only the CE's have special days and times.
@Overdcoat When a new update rolls out, it's my understanding its rolled out one section of the country at a time. Your receiver will automatically get those as they are released. If you want to force the NR, to verify you have the most up to date software, do a RBR and at the 'Hello' screen, press 0.2.4.6.8 on your remote. You will then see the download progress. It will DL software EVEN if its the SAME version. You will now have the most up to date version, even if you already had it.
