This bug is mentioned elsewhere, I wrote about it here (http://www.tivocommunity.com/tivo-vb/showthread.php?p=5581567&&#post5581567).

Would there be any way to get a workaround for this by setting something different in Videora? I have many files that I want to watch on my Series 2, but I can't stand seeing them squeezed. :(

Anyone contacted TiVo about this bug?

Nobody? :)

I couldn't find a workaround in pyTivo either, so I guess I'm SOL for now. :(

AFAIK Videora uses the FFMPEG libraries, I personally use FFMPEG via the command line interface. With FFMPEG you can force the output to be 4:3 and then put in your own black bars using -padtop & -padbottom to preserve the correct aspect ration for the 16:9 material. End result a 4:3 image containing a letterboxed 16:9 frame.

I think I read a post a while back suggesting that advanced FFMPEG options can be used through Videora somehow. I also have a windows batch file for the conversion which I can post once I get home.

Thanks, but aren't you guys both talking about displaying 16:9 content on letterboxed a 4:3 TV? That's what that thread was about, IIRC.

My issue is about displaying 16:9 content properly on a 16:9 display. Might have a similar solution though perhaps?

If you use ffmpeg with the 4:3 option, but without the padding and the correct output resolution for a 4:3 picture you'll get an image that's horizontally compressed on a 4:3 TV, stretched on your 16:9 display it should be back to normal.

The options would be:

-hq -target ntsc-dvd -b 6000 -aspect 4:3 -s 704x480

Did you try the update on the Transcode.py file as posted in the pyTiVo thread?

It fixed the no video problem for me and 16x9 works fine now (16x9 full screen on my 16x9 TV)

Thank you very much, that did it!

Woohoo... :)

Now off to try the pyTivo fix too...
