Re-create vcr cassettes with ruby 1.8.7
Re-create vcr cassettes with ruby 1.8.7

The cassettes created in 1.9.2 were failing to parse in 1.8.7, but the 1.8.7 cassettes seem to be forward compatible. Seems likely to have to do with changes to the YAML parser in 1.9 though I haven't tried to completely nail down the failure's source.
