Like many others, I'm still waiting for my mpeg4 channels.  My area
received Channel 1995 a few months ago and they said the cutover date was
maybe October or November (I forget now).  In any case, I'm a month after
the cutoff date, and so far, I haven't been able to find any channels with
mpeg4 just yet.

I have a HDHomeRun Prime and if you do get channel 1995, it does nothing.
Supposedly, if you have a cable box and tune to it, it pops up with an
interactive menu that will take you to a self-install kit request to
replace the old boxes.  Since I just have the HDHR, it just was a blank
screen.

Everything that I read says that the HDHR will pass the mpeg4 signal just
fine.  It would be nice to know when this is happening because I do
transcode things to mpeg4, so I can get rid of that step soon.

The only thing I know that you can do to test a channel is to tune the hdhr
to it, save the output stream to a file, and run a ffmpeg on it to identify
the stream type.  The other thing I've been doing is running
channel/frequency scans from the command line and doing a diff.  I'm
assuming that once the mpeg4 channels start popping, the existing lineup
will change.
