57, that is the problem with the Bell 6141. Changing the audio between DV or English does not solve the problem. I think that function only works for Bell Sat.Make sure you haven't activated SAP or DV settings on your STB.
I often wish I would have had the the 6141 instead of the 6131, because I do have an older TV in my house for the kids that has Coaxial input only (no composite connectors), and since the 6141 has the additional RF modulator output built in, it would cause a lot less clutter. I ended up having to connect the 6131 composite outputs to an old Radio Shack RF modulator my sister gave me, then from that a coax into my TV, and my TV on NTSC channel 3. It works just fine, but I would love less wires back there, ahh well, no big deal.It also has a coax output. Other than that, it's no different than a 6131. The only other difference between the 6131/6141 and 6400 are the 6400's lack of component outputs.
