RMVB fast forward and rewind?

Hi , I am able to stream rmvb format to my samsung 5500 led tv but i am having issues fast forwarding or rewind using the remote. Stop and pause button works without issue. Would like to cfm that this function is currently not supported for rmvb?
Thanks

yes. In the next versio you should be able to play the files natively, after a profile change, and that should enable seeking.
