i just bought a sony RM-V302 remote, and I have a samsung TV, and a zenith DVD/VCR/CD player that has its own speakers and such. I lost the original remote that came with the zenith system, so I bought the universal sony remote and the TV, DVD, CD and everything worked fine after I put in the right codes for them, but the volume doesn't change on the zenith system at all, it only changes on the TV. Is there a way I can make the remote capable to change the volume on the Zenith system? I would be extremely appreciate if anyone could help me with my problem. Thanks.
