Amar, ask your members
Put up a page, ask your members to vote.. link to the samples but do not give them a name. Like don't say this is the streaming version, download link, etc.. just...
Sample #1, 2, etc, then link to standalone pages, each with the unique option on it, again not named, but with instructions, like (right click/save as) only, or press play to start. Very basic stuff only.
Split test with different instructions and changing the order of the sample links, this should ensure the vote is more even.
If people still vote heavy on that download link, then you know it's not safe to remove, but if it's only 20% or less, than... I bet you could get away with it.
The top 100 programs only have a fraction of the traffic/members compared to the top tubes, which all streaming today. That influence has to bleed over.
