I think you got your information from Centova.com's v3 sales page, but it appears you are using v2 so I think that would answer many of your questions, I think this is the documentation you need
http://www.centova.com/pages/castdocs/ Yesterday I had the "Currently playing" (or Now playing) running and it was working for a little bit, and then it got stuck on 1 song until this morning. However, I was watching the "recently played", which was working just fine.
Is there something that would cause the Now Playing to "get stuck"?
For Centova v2 the widgets do not automatically refresh, however you can put them in a iframe and add a refresh tag
1. Create a html page and add your widget code, save as something like currently_playing.html -- add a meta refresh tag to the head,
ie <meta http-equiv="refresh" content="600">
2. add a iframe to your main web page and place it where you would like the widget to be displayed
ie.
<iframe src="currently_playing.html" name="current" width="260" height="63" frameborder="0" id="currently" scrolling="no" allowtransparency="true"></iframe>
For Centova v3 it uses AJAX so they refresh automatically without having to refresh the entire web page
Now I have read some posts about others that use Sam Broadcaster, in which I have been use Sam BC for the past 6 years, and was curious is there is a way for CC to interact with Sam in any way, mainly with how the config is setup and the now playing and requests.
Yes, depending on which type of auto dj your using Sam works with any SHOUTcast or Icecast server.
For SHOUTcast using Centova v2 you just need to enter your server ip, port and password into Sam (under encoders), dis-able source in Centova and then connect via Sam. The currently playing track and whatever you have entered in your encoder settings (ie. stream title, url, genre, etc.) will also update,
For Icecast using Centova v2 you enter your server ip, port, password and the mountpoint which is by default /live --- no need to disable source it will automatically detect the live source and switch from auto dj to live automatically
For Centova v3 you use the DJ manager, switching from auto dj to live is seamless with SHOUTcastv2 and sc_trans auto dj
Speaking of Requests... I seen that there is a "request widget" that works with CC. now I went and tried this out and (yes I did read about it first), It sends an email to the email address associated with the account, but How do you "put in" a song that was requested through CC Auto DJ?
So how does that actually work there?
Centova v2 only sends a email to notify the station owner, but the new Centova v3 is fully automated (one of my favorite features and a great selling tool), as long as the listener spells the title and artist correctly the auto dj will play it within whatever time you have entered in the config, I have tested this and it works well
In dealing with the Album Covers, how does CC actually read or find those? (I know sam bc you can attach them and upload them using Amazon, but how does CC get them? Do you have to upload them into the covers folder? Or upload them in the media folder along with the music?
You basically have a choice, you can enable Amazon Integration where it pulls the image from the Amazon database, this will also display a "buy now" link, if the ADMIN has his/her Amazon Affiliate ID entered they get credit for any sales that come through the server, the station owner can also have the option of entering their Amazon ID.
If not then Centova will extract the image from the mp3 tag, it stores them in the users files, it will create and store them in a folder /_covers
You just need to make sure you mp3 tags is correct, we recommend to our clients
http://www.mp3tag.de/ - it's free and makes it easy to correct your tags, although there are paid versions that will automatically correct all your tags for you.
