There is no need for you to create \AppData\Roaming\streamlink. This is specific to windows 7.
If you type on your command line: set, look what commes as APPDATA, this is XP's equivalent to
windows 7's \AppData\Roaming\streamlink,
C:\Documents and Settings\{username}\Application Data.

Streamlink will create for you location where it will place its configuration file.
Find where is your configuration file as in post #54.
If you look at default streamlinkrc file you will see that all lines are commented.
Streamlink can do without using configuration file if it can find VLC on your system.
If you want streamlink to use other player than VLC you can specify in stramlinkrc what other player you want
instead of specifying for every single usage on command line or batch file what other player than VLC you prefer.
Read streamlinkrc from beggining to the end and it will say something about what it is about.
FFmpeg and rtmpdump are optional, if streamlink doesn't install or installs them, I don't know
how it handles various situations it encounters.
You know if you want FFmpeg and rtmpdump or not, so specify in streamlinkrc where they are on your system,
if they are not on the %PATH%.
Type on command line: path, if you don't see your vlc, rtmpdump and ffmpeg there you MUST
specify in stramlinkrc where they are or streamlink won't find them.
