Will your code work.
Hi, jaga, i created a batch file with the same code , but i do not know how to drop and drop the mp4 file to this batch file. Hi, Jaga, i just saved the code as txt, and that was the mistake when i changed the same to bat, and drag and drop, a progressing glass runs and my video file size is mb hope to get the output , after an hour or so this is the progrogress.
Will i get lower audio quality if it converts to mpga, and i also do not know, if my tv supports it, as there was nothing like supported format in the TV manual Next coming to the main issue, when i drag and drop , it processed , but opens amachine language file, which when closes, vanished in to Really i do not know the trick, to give or change the batch files.

Would it be possible to print this entire article as a PDF, so we can read it and go through the install steps without having to deal with web browsing? That would help greatly. You open them in Adobe Acrobat or Acrobat Reader.
I suspect the problem is that a mutant font was used for the text on the web page, one that has no equivalent in a standard computer, and that text is all that the PDF printer could interpret. It would be simpler if you, Mr. Zahl, could print it from your original, using your own PDF printer, and making sure the fonts are included with the PDF document so it can be read and printed out. Or use a nice standard font like Times New Roman in producing the web page, but of course that ship has sailed.
Ran into the same situation with a multi-page program book where the font could be included, but when printed, it turned out that the font was prohibited by the font creator from being used in a PDF document. Had to find a similar-looking font to substitute throughout the document at the last minute. A kluge, but it worked. And I will never use that font again. You can drag a PDF into chrome to display it there.
I thank you for the PDF. Fixing those for printing in projects is always problematic; it would be better if Adobe actually made Acrobat printers cheap, instead of sticking up the consumer. My sincere thanks for you taking the effort, Mr. And another thing.
