This is effective as of Mechbunny Tube Script 6.0.5
To enable VOD System:
1) Set Vod Tokens to "true" in admin area settings page under Payment Gateway settings. Billers should all be set to "false" - these settings are used for monthly membership sites.
2) Set the video rental length in seconds in the same spot. By default it's 86400, so 1 day. If you want permanent purchases, just enter a very large number such as 3153600000 (100 years)
3) Define the default token cost per video. If you set this to zero, all videos will default to "free". You can overwrite a single video's token cost under edit content for that video. For example, if you want to make all videos free except certain ones, you would leave default token cost at zero and enter "5" or however much you want under edit content for the content do YOU want to bill for.
4) In template.buyTokens.php, adjust the links/template here so it links to your billers purchase tokens page.
5) Setup biller postback script using the functions located in admin/functions.billing.php as per your billers postback documentation.
