Help me!!<br />
<br />
By accident I have opened &nbsp;a video_ts.ifo &nbsp;file which is a windows dat file &nbsp;in notepad.<br />
As the flag was on &quot;always open with&quot; &nbsp;all my ifo files have changed into notepad.<br />
How do I change them all back to the original.<br />
I have tried to open them again with Appfix Apphelp installer but that gives an error.<br />
because of this I can't burn the VIDEO_TS map as a whole anymore.<br />
Help!!!
