Some M3U files have an EXTM3U url-tvg tag which contains an external M3U file.
The URL to that EPG is prefixed with the proxy, however URLs that are within that EPG aren’t.
Before proxifying the M3U, download the EPG, proxify those URLs and save the EPG in the static folder. Then replace the EXTM3U url-tvg tag with the new EPG.
