Netflix Woes

I have had Netflix for a few months now. Since my NYC videostore of choice, TLA, had to close (why oh why!?), it is now my only video rental source aside from the New York Public Library. I haven't had too many problems with Netflix, but I have had some broken discs (about 4 now in roughly as many months). Two of these discs--the original and its replacement--have been The Mad Songs of Fernanda Hussein. Could it be that someone out there is wreaking havoc on discs of this film (whether for its politics or its aesthetics)? How much has this been a problem for other Netflix users? Is there ever any kind of penalty, i.e., will they suspect me if I report too many broken discs? Because I really want to see Fernanda Hussein, among other broken discs, and I'm afraid to request a third disc for it.
