These hosts use api for Android apps. So, they not parse web site content.
1. Live Streams are blocked with my IP. So, if you have problem with radio streams please provide debug logs
2. I do not see any problem with jumps using keys 3, 6, 9.
You could have problems beacuse you use wrong player which is not able to valid handle HLS/M3U8 streams.
You should use exteplayer3.
If you not able to do this you can change the host configuration (under blue button) to prefer MP4 format, by changing option "More important" to "format".
P.S Much more better option to jump video is to hold on left or right windrose and choose time to which you want to jump
