I'm loving lots of the new features and fixes! I'm testing the latest version of the player and am working through a list of many questions, of which I've found or worked out answers to quite a few, but the following I haven't yet:
1) Initially, after upgrade, no videos would play. I'm using Adobe Flash Media Streaming Server 3, which was fine in version 3.15 but now something has changed.
I'm currently using the player's native bandwidth detection and XML playlists. In the playlist I'm pointing <location> to the RTMP stream and <identifier> was the name of the video file (minus extension) before bandwidth detection suffix. The player was then choosing the correct file from the detected bit rate.
i.e.
<location>rtmp://123.456.123.456/mystream</location>
<identifier>myvideo</identifier>
...then the player was serving up the correct file with the relevant suffix according to the bandwidth detection test,
e.g. 'myvideo_512.flv' or 'myvideo_256.flv'.
Now it seems the only way I can get anything to play is to do something like the following:
<location>rtmp://123.456.123.456/mystream</location>
<identifier>myvideo_512</identifier>
i.e. hard-code the full file name (minus extension) so no bandwidth detection is taking place. What am I doing wrong?
2) I'm wanting to show an image at the end of every video with a kind of "what to do next" sort of thing, where this could be anything from "visit an external website" or "view another video" or whatever.
the <commercial> tag is looking promising for this and I'm doing something like the following in the playlist:
<location>/images/what-to-do-next.png</location>
<album>commercial</album>
Only I have two problems:
2a) Can I make the image show indefinitely without the playlist continuing onto the next video? If not, where is the 4 seconds(ish) that it is displayed for defined? Can I extend this to a much longer time period?
2b) When using <commercial> the controls are automatically disabled, can they be re-enabled somehow (flashvar etc...)? I want to display this image but not to prevent viewers from selecting another video in the playlist etc...
3) Is the 'midroll' function only per playlist rather than per playlist item (video)? Would be nice if I could have a different set of adverts or messages display per video but I think this is a secondary thing at the moment.
Many, many, many thanks in advance! I hope all of that makes some sort of sense. :)

1) I don't have FMS to test against, so I can't help you with this one.
2a) set the rotatetime flashvar maybe to indefinitely=999999999999999999999999 ???
2b) don't use the commercial element, the item will show in the playlist, but that shouldn't be a big surprise.
3) the midroll value is picked up if you use:
<meta rel='midroll>some_midroll.xml</meta>in the playlist track, but it doesn't display the midroll —— short answer = NO.
