[FFmpeg-user] Unable to play VOB file with audio.

I have a vob file that plays just fine but no audio as my DLNA TV does not
support the DTS format

Input #0, mpeg, from 'test.VOB':
  Duration: 00:18:50.66, start: 1148.989333, bitrate: 7595 kb/s
    Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p, 720x576 [SAR
64:45 DAR 16:9], 9000 kb/s, 27.21 fps, 25 tbr, 90k tbn, 50 tbc
    Stream #0:1[0x89]: Audio: dts (DTS), 48000 Hz, 5.1(side), s16, 768 kb/s
    Stream #0:2[0x80]: Audio: ac3, 48000 Hz, 5.1(side), s16, 448 kb/s
At least one output file must be specified

As you can see, the first stream is DTS which is not supported but the
second stream is supported. So what I want to do is create another VOB file
and use the video as is and the second stream from the audio. So I did, 
/volume1/@appstore/Serviio/bin/ffmpeg -i test.VOB -i test.VOB -map 0:0 -map
0:2 -vcode
c copy -acodec copy -y test-copyav.VOB

The resulting file now does not play video but the audio is fine. (Reverse
of the original issue). The output of the new file is:

Seems stream 1 codec frame rate differs from container frame rate: 50.00
(50/1) -> 50.00 (50/1)
Input #0, mpeg, from 'test-copyav.VOB':
  Duration: 00:18:51.14, start: 1.042667, bitrate: 6780 kb/s
    Stream #0:0[0x80]: Audio: ac3, 48000 Hz, 5.1(side), s16, 448 kb/s
    Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p, 720x576 [SAR
64:45 DAR 16:9], 9000 kb/s, 27.14 fps, *50 tbr,* 90k tbn, 50 tbc
At least one output file must be specified

The only difference i see is the TBR is 50 in the new file and 25 on the
original. Is that the reason why it is not playing video? If so, is there an
option to force the tbr value. Am I doing something wrong in the above step?

Thanks for any help.
