For a YouTube channel to Miro conversion form, click here.

Some Miro-related tips:

1. Don't use Miro's subscribe-to-search results feature for YouTube searches. Instead, use the special channels that Google provides. For more information, click here.

2. Before using the program, go through the options on the Video  ->  Options screen. On the Downloads tab, set BitTorrent upstream to 5 or 10. If your ISP has given you a generous bandwidth allowance, you can set this number higher. On the Disk Space tab, set expire time to the value that you prefer, or Never if you'd like to save videos forever. Warning: The Never setting will use up a lot of disk space.

3. If Miro has trouble downloading a particular video and keeps retrying, cancel the download. If you don't cancel problematic downloads, the program will use up a lot of bandwidth, and your Internet Service Provider may complain about it.

4. There's a Settings button on every channel page. Press the button and you'll see a per-channel options screen. You may wish to uncheck the Don't Auto Download checkbox.

Note: This is not a “portable” application. However, it's a FOSS program.
