I get the same behaviour on Maverick, except that theora will not even work.
The terminal spits this out when rendering: ERROR [ 3396] [0x7fa324408700] "<Pipeline at 0x2fb5d10>" pipeline Apr 25 18:50:49 _errorObject: error from /GstPipeline:pipeline1/GstBin:bin1/GnlComposition:gnlcomposition2/GnlSource:gnlsource: FileSourceFactory0/GstBin:bin2/pitivi+elements+singledecodebin+SingleDecodeBin:pitivi+elements+singledecodebin+singledecodebin0/GstAviDemux:avidemux71 (__main__.GstAviDemux): GStreamer encountered a general stream error.
