Hmmm...
your file looks fine.
tibineagu are you on a non-trial version now? As I stated above it won't work for the Trial version.
btw, installing a codec to decode mpeg2 won't help. Adobe uses an internal decoder that wins the vote as to who gets to do the work. So even if you have an mpeg2 decoder codec installed it won't win.
This is a matter of royalties. Adobe pays a royalty for every installation that supports MPEG2 (as well as formats that use other codecs). So management for each point product that installs AME decides whether to include the full set of formats or only a limited set of non-royalty bearing codecs.
If you have one of products that installs only the limited set, then there's currently no way to add codecs--short of buying a product or suite with the full set (Premiere Pro, After Effects, Production Premium, and Master Collection). I'll submit a feature request to provide a way for customers with the limited format set to purchase the royalty-bearing codecs.
This is bug of AME. I capture sample by eMPIA USB 2.0 Video Devices EM28xx.
