Generate M3U Playlist for SiliconDust HDHomerun Tuners

ReadMe.md

SYNOPSIS

Creates an M3U playlist for an HDHomerun tuner

DESCRIPTION

Downloads the lineup from an HDHR tuner, specified by IP address and transforms it into an M3U plalist

When you don't specify an output file, the m3u content will be printed out for preview.

The output file will be generated as UTF-8 without BOM, which isn't the case when you just pipe the output into a file!

PARAMETER $ipaddress

The IP address of the tuner

PARAMETER $outfile

An optional filename to which to save the M3U

.EXAMPLE

C:\PS> 
.\hdhr_get_m3u.ps1 192.168.1.1 out.m3u

.EXAMPLE

C:\PS> 
.\hdhr_get_m3u.ps1 192.168.1.1

Why not just use

http://hdhomerun.local/lineup.m3u http://HDHomeRun-device-name-here/lineup.m3u http://HDHomeRun-IP-here/lineup.m3u

The list gets exported from the units it self directly ?

Hi sorry to bother so do you have to put the dash before the ip address?
