Yes, the video posts look OK, except for there being like 6 versions of the original one xD
@firstname.lastname@example.org I noticed the same server deficiency for GNU Social also.
This is an effect of the "guaranteed message delivery" from #AndStatus side and "duplication problem ignorance" from the Server side.
I hope pump.io will fix this some day @email@example.com ?!
The long story about duplicated posts, caused by communication problems, is here: https://github.com/andstatus/andstatus/issues/83
