I'm still trying to get a proper back trace, in the meanwhile I attach Windows' error report.<br>It seems that the error is in x264 and that the actual message is:<br>
<p class="MsoPlainText"><span style="font-family:"Courier New"">"sh"
non è riconosciuto come comando interno o esterno,</span></p>
<p class="MsoPlainText"><span style="font-family:"Courier New""><span style> </span>un programma eseguibile o un file batch.</span></p>
Which translates more or less into ""sh" is not recognized as an internal or external command, an executable program or a batch".<br>Yours,<br>Marco<br>
