We recently got a Directv Tivo unit and wanted to have a Tivo compatible remote for both of us for all our stuff. The PMDVR8 is a good unit. It controls our DVD player, VCR, Directv - Tivo box and our Magnavox/Philips TV without a hitch.We don't have a volume control problem with the TV with this unit. We did have a problem with the original Tivo remote but then tried a different TV code number and that fixed that problem.The device / code number list included with this unit is impressive and all our devices programmed in without having to resort to "learning" anything.We will be buying another one, for a spare, in case the dogs mess one of them up.
