If speed is the problem you can put dvdplayer output to a file and then send it to
the DVB card:

touch tmp
dvdplayer -a 0 -c -f /dvd/video_ts/vts_01_1.vob -d tmp
cat tmp > /dev/video

Use this option if you have sound without interupts and if you have video
disturbances only with Dolby Digital 2.0 streams.
For example option -j 10 sends 99% sound samples to the DVB card.
