I was actually sampling the files before they were completely downloaded. It happens on about 1 of 4 files -- I can tell when it switches over, for example it will play 10 seconds of one part of the song, then 5 seconds of another version, then go back to the first version. In watching how it was downloading it, it matches when it was swarming from multiple download sources. Is there not a registry setting or ini file change that will disable this? Are there any previous versions of LimeWire that do not use this technology that still work on the latest Gnutella system? This problem is separate from the corrupted prompt.
