You can now use the input option "-r 30" to remux 
this stream with "correct" timestamps.
(I am not sure if they will really be correct but 
playback works fine here.)

The output will never be perfect because you have 
reception errors in your input stream. Consider 
using mpegts which allows such errors, I suspect 
all other file types are invalid whenever such 
errors occur.
