Anybody done this? I use MusicMatch Jukebox and paid $20 for the "Plus" upgrade to accomplish this. The tape is in good condition, the recording is about 60 minutes long. I monitor during recording from cassette (boom box) to computer via speaker or headphones and sounds fine. When I playback from the computer the recording slows down noticeably about 5 minutes into it. The tape is not affected. Have tried different qualities and different file formats all with the same result. Any ideas?
