What OS are you using? (As I saw your log, you were using Windows.)
Can you try the following:
- enable/disable hardware decoding? (setting -> all -> Input/Codec -> Video codec -> FFmpeg)
- change threads number from 0 to 1 or 1 to 0? (setting -> all -> Input/Codec -> Video codec -> FFmpeg)
- change video output from default (Direct3d) to another?

On my Windows 7 64bit environment (Video Card: Radeon 5870 Catalyst 12.1 Preview):
- If I enabled hardware decoding, I saw many block as you said.
- If I disabled hardware decoding, I didn't see block, playback was fine.

Maybe this issue is realated to the ticket (at least for me) : http://trac.videolan.org/vlc/ticket/5676

Thanks i tested everything like different video outputs and disabled HW decoding... nothing, BUT now i can confirm that when using 1 thread everything is fine with cost of slower video(even 1.1 plays normally). Now developers will know that multithreading causes problems and they can fix it now.

Developers may use my .mts file for testing.

This file seems fishy to me but I'm not sure what is going wrong.
Remuxing to M2TS and even to MP4 or MKV doesn't help, and you can see the image kind of 'jumping' in a non natural way as if it had interlaced fields badly stamped. I believe the H.264 elementary stream has something special and Fenrir should have a look at this sample.
