VBox 3442 woes

Live TV & DVR

Server Version#: 1.40.3.8530
Player Version#: 4.131.1
Tuner Make/Model: VBox 3442

I’m trying to set up live TV using a VBox 3442 tuner. I have the VBox set up and tuned in, but I can’t get Plex to talk to it.

Plex says: “We couldn’t find any hardware we recognize, but will continue to look for available devices.”

At the same time the VBox logs say:

Jun 10 10:42:08 VboxUpnpMediaServer: (084) [UPNP_SRV] [A]
PlexMediaGrabber::VboxProcessHttpGetRequest - not Plex Request
Jun 10 10:42:23 VboxUpnpMediaServer: (515) [UPNP_SRV] [A]
PlexMediaGrabber::VboxProcessHttpGetRequest - not Plex Request

VBox support are not really helping - they’re suggesting I set up SMB1 on my NAS, which just seems completely orthogonal to the actual problem.

I bought the VBox because it’s described as a supported tuner for Plex. Any pointers?

Anyone?

Is there any further information I can provide to help figure this out?

Still hoping for an answer here.

Are your tuner and Plex server on the same logical network (VLAN, subnet)? PMS discovers tuners by sending an SSDP discover request to the multicast address 239.255.255.250. It then awaits responses from tuner devices (among other things, depending on how the server is configured).

You could try running tcpdump on the server to see what it shows. Something like:
sudo tcpdump -i <interface_name> -n -A -vvv port 1900 and host <ip_of_server>

It should show the discover requests sent by the server and any responses received. Here’s an example from my server and HDHomeRun tuner:

17:17:28.323862 IP (tos 0x0, ttl 1, id 6830, offset 0, flags [DF], proto UDP (17), length 129)
    10.10.0.104.38264 > 239.255.255.250.1900: [udp sum ok] UDP, length 101

PMS then queries the location URL returned to find the relevant details from the responding device to see what it is. You’ll sometimes see loging from PMS to the effect that it received an SSDP response from an invalid/unknown device.
