Tuning error with no SDT present

Janne Grunau requested that I open a ticket for this which he helped me debug. The problem is with tuning a DVB channel which has no SDT (or NIT for that matter). Happens on PBSHD on AMC3 in the US. This is against the mythtv-eit branch.

If it doesn't have a SDT it is not a DVB channel.

Are you sure it is not an ATSC channel?

Even if it is not it should be caught by the "Check if this is an MPEG channel" code a little later in tv_rec.cpp (int mythtv-eit).

Daniel, the currentOriginalNetworkID is initialized with -1. After the automic cast to uint it is something greater 0. So it tries to tune to the channel as DVB channel and gets never a lock since the SDT is missing.

(In [9925]) Fixes #1769 in mythtv-eit. If the netid is -1, with this change we fall back to MPEG tuning rather than try DVB tuning with the invalid netid.
