First you can put the exe for the d/l anywhere. Second I put the addin into the TCPMP dir. Then I opened TCPMP and assoc the flv format and closed it. Start the d/l software and leave it running in the background. Then you log onto youtube and pick a clip. Copy and paste the id (address) into the space called out in the d/l program and start the d/l. After that go to where you saved it and play it.
