I just burnt my first successful DVD using mythweb and mythburn (under R5A22)

One issue, the video is full screen on my 4:3 tv, but the original show was 16:9. There was a warning in the log file concerning this...

WARN: attempt to update aspect ratio from 4:3 to 16:9; skipping

although the wording in the warning seems backwards?

Just one thought - this isn't because I have the default zoom mode for mythtv playback to 'FILL' is it?

Anyway, how can I make my DVD's in the original 16:9 as recorded from my DVB-T card?

Me thinks someone is going to have a nice write up to post on the wiki once he has everything running right (or at least the way he wants )...

OK, that's fair enough. Only to happy to give a little back.

I've been sneaking peeks at the mythtvburn.sh script, and I think the 4:3 aspect ratio is hard coded in it. Could it be as simple as a quick edit in these two places?

firstly,



and

I think those two aspects are just for the shape of the menu screen, and the chapter buttons on it.

On the disks I burn (with a much older version of the scripts), I have no problems with the playback shape. My DVB-based recordings are 16:9, and they play back correctly on a 16:9 TV (when the DVD player is configured for 16:9 too).

The only annoyance is that 4:3 material (which has black bars left and right in the 16:9 frame) has double black bars (i.e. top and bottom too) when played back on a 4:3 TV. I could fix this, but using the zoom key on the DVD layer is easier.

I am sure you're right. I just altered the script and it didn't fix it.




OK, it could well be the version I am using, as I upgraded from the new ones in R5A22 (which didn't even work well enough to produce a CD at all - possibly due to permissions I was told). I upgraded to the current cvs version very recently.

I am doing all this from mythweb, so it's using mythwebburn, but that uses the same mythtvburn.sh I think.



I could live with that too.

Well, I'm up my neck in the scripts now, and only partially understanding. However, in the remplex.sh script there's a section with multiple choices for remultiplexing the video. By default it uses Project X, but there some DVB specific alternatives.




Is this the process where the aspect ratio is being changed? Is it worth trying replex? Or one of the others (what does iso13818ps do?)?

I would like to as a question to this group.
I have 640x480 recordings and I want the dvd to keep that resolution and aspect ratio, since I have a 4:3 TV.

ffrr, if you made you recording 16:9 and it is full screen on your 4:3 tv then I have the opposite problem.
Maybe there is a bigger issue when it comes to mythburn and the dvd it creates.

I'm by no means a DVD expert, but that isn't a valid DVD resolution. You'll have to use some software to enlarge or provide borders.

I am no expert either, BUT nuvexport (using ffmpeg) can produce a DVD that displays 16:9, and maybe it is letterboxed, but all you do is change one number in a script (the aspect ratio of course).

ffmpeg/DVD.pm (in /usr/local/share/nuvexport/export/ffmpeg)make the following change:
In the section marked:



So I am just looking to produce the same thing from mythburn.

I believe I've had the same issue, and identified the cause, if not a complete solution.
