Hello Monks,

I have in my possession a Microsoft Powershell script which examines all the files in a folded ending in .wtv (Windows Media Center recorded TV programmes), extracts some metadata (using a DLL called "Toub.MediaCenter.Dvrms.dll") and then writes it to stdout.

[void][System.Reflection.Assembly]::LoadFile("C:\Toub.MediaCenter.Dvrm
+s.dll")

# Get all files ending in .wtv

foreach ($file in gci "*.wtv")
{
  $wtv = New-Object Toub.Mediacenter.Dvrms.Metadata.DvrmsMetadataEdito
+r($file)
  $attrlist = $wtv.GetAttributes()

  # Extract the Title and Description from the recorded programme

  $t = $attrlist["Title"].value
  $d = $attrlist["WM/SubTitleDescription"].value

  # Print them to STDOUT

  "$t"
  "$d"
}

At the moment, I run this from a Perl script and then parse the results. It works, but is messy and I'd like to drop the powershell part and do it entirely within Perl.

However, I have absolutely no idea how to link to a DLL so that I can call "GetAttributes" method on a file and then extract the values of "WM/Title" and "WM/SubTitleDescription".

Can anyone please advise me on how to do this?

Thanks in advance!
