Certainly  On httpwwwdavidstrathairncommediafilmhtml there are several WMV files taken from HBO specials  Those belong to and are copyright from HBO and I see no used by permission there  I see a note that says No copyright infringements intended but that doesnt say that its NOT a copyright infringement  just becaus ethey say they didnt mean to doesnt mean it didnt happen On the same page there are also copies of featurettes from commercially available DVDs  These too will be copyrighted One httpwwwdavidstrathairncommediatvhtml we have whole scenes taken from the HBO show The Sopranos  those are copyright HBO too and again I dont see a used with permission anywhere On httpwwwdavidstrathairncommediaradiohtml there are all sorts of excerpts from radio shows which are owned by the respective stations  I see no permission given there either  There is not doubt that all of these clips are copyrighted by the original owners  there is no evidence that they are posted with the owners permission  Therefore this it is a reasonable conclusion that this is a copyright violation barring evidence to the contrary
