as the title says,neither the number buttons nor holding the FF button and then typing in a number will FF the stream when its RTMP when using Openpli 4.0
to test this try any stream from BBC iplayer or from the Ondemand plugin.
this is just an Openpli problem as the above works perfectly when using the BH image.
as far as im aware this is on all boxes,but personally ive only tested on VU+ boxes.
