I didn't get that impression at all from watching the clip on Youtube. Mr Lamb explained many times why they decided not to air the speech as Savage didn't actually give a speech, but rather sent in a DVD both to the awards banquet and C-Span. And it appears to me this whole brouhaha was designed by Savage to get people to buy the DVD of his 11 minute speech. I'd never heard of Mr Lamb before, but he seems to be a fairly decent type of guy. And as for reading the worst of the worst emails, conservative talk show hosts are just as guilty.
As I said, I have seen C-Span run 2 hours of PowerPoint presentations, and they always show DVD mini-films at political events. His explanation was nonsense.
