There is a plugin for ATSC:

It is a patch to vdr to use ATSC and it has a scanner to scan for channels and create a channels.conf. Current HG version also lets you select which tuner is used for channel scanning and select between atsc and cable. I currently am having problems with this version segfaulting when trying to scan, but it seems to be ok for others. Also, the cable scanning part is still in the works. I tried scanning my cable with another program and found some 300+ channels, but with the plugin, while it was able to tune a number of frequancies, only found 5 local channels.

  On my first thought I considered to take 'A' for 'analog', but since there
is something like "ATSC" (and I know nothing about it, if it's supported by
vdr or is covered by dvbdevice or whatever), perhaps I should use another
one?
  So I think it would be better to take *'V' = 'analog video'*, since
pvrinput is basically an interface to v4l-devices.

"ATSC is a set of standards developed by the Advanced Television
Systems Committee for digital television transmission. ATSC replaced
much of the analog NTSC television system[1]  in the United
States[2][3]  on June 12, 2009 and will replace NTSC by August 31,
2011 in Canada[4]  and December 31, 2021 in Mexico."

Yes, I think you should take ATSC into consideration unless you want
to ignore North America. ;)

Except ATSC is a subset of DVB.. At the moment ATSC is flagged as T,
which I think it should be..

For people that don't really know, ATSC comes in two flavours (or
flavors), Over the Air, and Clear Qam.  Over the air is using a roof top
antenna, like DVB-T, then we get Clear Qam, where you plugin the input
from your cable company.  By law all cable companies must provide clear
(ie, non encoded) local channels.  However, Comcast in our region has
just released a "Basic Digital" package, which means we get about 60
channels now Clear Qam, including stuff you would have thought would be
encoded (and is on Euro Sat).

If you don't want to mess with Nagra-3, card readers, and such like,
it's the best way to get VDR showing useful programming.

Now, if only there was a channel scanner that could write a VDR style
channels.conf with ATSC..

Just in case someone is searching archives, the best way to work out
what you should have in your area is to look at the silicon dust website
(the manufactorer of the the hdhomerun devices.  These will show you (by
zip) for OTA and Cable..

My zip code is here:

A channel scanner won't always find the info you need for Cable..

I had to manually insert several Vpids (which for my area were one less
than the apid) and turn off auto update.. I then had to tell VDR they
were type =2..


Maybe I'll do a Comcast-VDR howto sometime..
