My Roku is skipping 3 to 4 spaces at a time in any direction don't think it's just remote because we have a Roku in our son's room on opposite side of the house and it's doing it on both... any ideas??
This may not work for everybody, but many people with your problem have eliminated the problem by restarting the Roku. (Note that if yours is a Roku TV with "Fast start" enabled, turning it off and back on just puts it into and out of a standby state and does NOT give you a complete restart.)
Depending on your Roku model and Roku version number you'll find the "System restart" option under "Settings > System > Power" or if you don't have a "Power" option, under "Settings > System".
If a restart doesn't do it, or if you don't have sufficient control with the remote to navigate the Roku menus, you can also restart by pulling the power plug to the Roku for a few seconds then plugging it back in and waiting for it to restart.
