Hi Vince and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, is this the original remote that came with the VSX-1017?
Have you considered / tried a RESET of the remote? ...of the unit itself?
Can you please click HERE and give this a try?
Will the Pioneer work as expected using the front panel controls?
Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.
