Mp3 Encode/decode On Media File Context Menu

[NaTrIuM]

Hello everyone, I don't know if this is the best place to post, but I didn't want to clutter the Registry Tweaks sticky as this hasn't got much to do with a windows tweak.

In the making of an unattended instalation I decided to include the lame.exe MP3 encoder on my system32 directory and use context commands associated to the .wav and .mp3 files.

This is the contents of the registry file that does those changes:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\SoundRec\shell\encodefast]
@="Encode to MP3 (Fast)"

[HKEY_CLASSES_ROOT\SoundRec\shell\encodefast\command]
@="\"lame.exe\" -f \"%L\""

[HKEY_CLASSES_ROOT\SoundRec\shell\encodehigh]
@="Encode to MP3 (High Quality)"

[HKEY_CLASSES_ROOT\SoundRec\shell\encodehigh\command]
@="\"lame.exe\" -h \"%L\""

[HKEY_CLASSES_ROOT\mp3file\shell\decode]
@="Decode to WAV"

[HKEY_CLASSES_ROOT\mp3file\shell\decode\command]
@="\"lame.exe\" --decode \"%L\""

I've tried to add the 'shell' keys to HKEY_CLASSES_ROOT\.wav and HKEY_CLASSES_ROOT\.mp3 but they didn't work.

The problem is that when the default value in HKEY_CLASSES_ROOT\.wav is changed from SoundRec to another media player, foobar2000.wav for example, the context options stop working.

I've already searched but I didn't find anything helpful.

Is there any way around?

Thanks in advance.
