New Post: DVBLink recordings metadata

More on this for anyone using it... I was getting failures where shows didn't have a season/episode or a subtitle set so have added original broadcast time in this case. However, as argus TV files don't support this I've had to switch to creating nvpr files.

All works fine but I suggest removing the 'download metadata' option for the profile.
