[mythtv-users] Nuvexport dvb-recordings to DVD, problem with aspect ratio

[Sami Röppänen]

Hello,

I have used mythtv for DVB recordings. I live in western europe, so the
transmissions are in PAL format. I have configured the capture format to
be 720x576 in resolution, because I heard that's my cards native capture
format. I have tried both rjmpeg and Mpeg4.

When I tried to export recorded shows (with nuvexport-dvd, current
version) to be burned to DVD, I faced a problem; my newly created
mpeg-files become distorded in their aspect ratio (meaning that they are
"flat faced" (people seem too tall)).  There is also blank space on the
left and right of the screen, for about 30 pixels each. I've tried to
edit my /etc/nuvexport.rc with no luck (I've included that files
<DVD>-region on this post).

Note that this is purely Nuvexport problem, the shows that are not yet
exported play fine and with correct aspect ratio in mplayer or in
windows, with nero mediaplayer. And it's not a problem with my
DVD-authoring tool either, infact QDVDAuthor complains about an unknown
aspect ratio.


The /etc/nuvexport.rc:

<generic>

    path = /part3

    use_cutlist     = yes
    multipass       = yes

    noise_reduction = yes
    deinterlace     = yes
    crop            = yes

</generic>

<DVD>

    vbr          = yes   # Enable vbr to get the multipass/quantisation
options
                         # (enabling multipass or quantisation
automatically enables vbr)
    multipass    = no   # You get either multipass or quantisation;
multipass will override
    quantisation = 5     # 4 through 6 is probably right...  1..31 are
allowed (lower is better quality)

    a_bitrate    =  384  # Audio bitrate of 128 kbps
    #v_bitrate    = 960   # Remember, quantisation overrides video
bitrate

    width        = 720   # Height adjusts automatically to width,
according to aspect ratio
    height       = auto

</DVD>

---Notes;

I have tried tweaking above width and height with no luck as of yet. For
example changing width to 768 (as someone in this list succested). But
still I think the problem lays in this configuration file. Anyone had
luck exporting DVB pal recordings to DVD, and with what
resolution/video-options?
