Tvheadend

Hi,

I have TVHeadend running nicely on a Raspberry PI / OpenElec.

I can watch TV (Freeview) from any machine using Kodi/XBMC, and from TVHClient on my phone.

However, while on some Windows machines I can watch streams directly in VLC (just putting in the URL or alternatively using an M3U playlist), on some other Windows machines, running the same version of VLC, they won't open. On these machines, when I put the URL in a browser, it tried to download the MP2T file rather than trigger a player (and if I tell it to open with the player, it doesn't work).

Clearly some codec or of the like is missing but I can't figure out the difference between the machines. VLC is 2.1.3 (Rincewind). Windows are all Windows 7.

Any suggestions welcome!

Thanks.
