Not sure, but the format of the .ts file is very peculiar.
Looking at the file with Medianinfo shows no video content at all
Just recorded a couple of mins on a non-freesat box and mediainfo says:

Don't know if this is any use. FWIW on a quick scan it looks more or less identical to Starplus HD when it was FTA for a day or two.
