Description of your issue, suggested solution and other information

Description cannot be extracted for provided URL. Warning is thrown.

[isaacm]

The sample video link provided doesn't include a description in the scraped data. According to REAMDE.md the description field is optional and a warning is emitted when a description cannot be parsed.

Otherwise a default value can be added when an imdb trailer description is not present by setting a sane default here.

Ok, great, thanks @isaacm. The warning seemed to suggest this might be a parsing issue that might require a fix. I'll do as you suggest and close this.
