[quote name='thabizzle']I have the 360 connected to video 2(component cables) and the DVR is connected to video 3(composite) Changing TVs is not an option. I have a 32" JVC.[/quote]
If you have more than one TV, I meant move the 360 to that tv to just test it.
Also try just disconnecting the DVR and fire up the 360 to see if it still does it
Either way, they're both on two different inputs, there shouldn't be any interference.
