the files are recorded to my flash drive from my converter box, and later downloaded to my computer, to play the files use VLC media player or splash lite but this time just played the file with the splash Lite and used the print screen key for copy and paint for paste the image and later too save it to the computer.

Well our DTV system is the Japanese Brazilean system and really is not the best .

The recordings was made between 11AM and 2PM CLST (chilean standard timezone). the gossip show time, morning shows and later 1-2:30PM news time

unfortunatelly i do not have the way of show up or capture the signal waveform or shape under an spectrum analyzer, if had one i would do miracles with those DTV channels, but why do you need the waveform of those tv channels,

Jenkin, the waveform will look like any other ISDB-T or DVB-T waveform on a spectrum analyser; basically its looks like a tall flat-topped mesa or column that is 6/7/8Mhz wide depending on country.
