Error scanning Saorview DVB-T channels

[happybluegreen]

Hi,

Running nextpvr amd64 docker container with TBS pcie tuner card.

When I scan for saorview channels in nextpvr it encounters an error parsing the scan data see log output below.

Seems to be a bug in parsing the channel info:

I actually just saw these errors on another thread this morning crashing the server. Sub will need to look be it comes from the scan
