mm I have tested with delphi 7 (I have Delphi 6 Pro and delphi 7 Personal....but i find delphi 6 is more stable as delphi 7)
but under both Compilers it works fine...
But I did download (and unzip)(and place all DLL's in windows/system and all *.dcu's in the program directoy)
You will mean *.pas or ??
Don`t forget you have 2 possible ways
1.) put all needed Pas Files (with the calls for the dll`s) in one directory and add this directory to your searchpath
2.) put all needed Pas Files (with the calls for the dll`s) in your program directory
When I run the RECTEST demo I get a delphi error BassEnc.DCU not found.
It seams tthat you have forget to put the bassenc.pas to your searchpath resp to put it in your programdir
