the OSMF player that ships with Wowza didn't work well with a ?DVR manifest file... but the others did, thanks.
Curious, which OSMF player that ships with Wowza isn't working well and what behavior are you seeing?
Also, what players did work well?
There have been some changes to the html wrapper around the various OSMF players that we ship as examples to provide larger buffers for live streaming. Make sure you have the latest example/LiveDvrStreaming/*.html and *.swf files.
