Is the binary addons repo used for the Nightly builds any closer to being up to date than the normal release channel? It is very difficult to test anything PVR related when the addons are several releases behind.
Yes, the binary addons are more up to date than in the stable repo.
Due to the nature of nightly builds (the same goes for the addons), you should expect things to break or not working as stable as expected.
Why in the latest nightly builds is no tar file for odroid c2
Builds were unified, use the S905 tar.
