Can you show us the logs when you play the file you cannot get a time?
Please open Tools -> Messages (set Verbosity to 2) before you start the playback and then paste the full resulting log here or on Pastebin.com.
The log below is for a clip encoded just above the bubble, at 52mbps, for test purposes. It is encoded with identical settings, other than bitrate, to a working 50mpbs file.
