Aggregator and YouTube RSS

I was wondering if it is possible when aggregating from an RSS feed to not have it delete nodes after 12 months. Also is it possible to have youtube videos be stored in a node type that is made for videos that are grabbed from a specific users RSS.

What I am trying to do is pull back all my videos from youtube and have drupal display them. I want the site to grab the videos on it's own with aggregation and a cron. Is there any combination of modules that allows this. I looked around and didn't see anything that looked close to what I was looking for, they all seemed to expect you to manually add the node instead of grabbing the information from the RSS. Is this possible or will I have to build a custom module.

Thank you,
Jenn
