HDTV partial success

Finally, managed to find out a partially working configuration.

dvbscan was not able to detect the vid and aid correctly. The correct channels.conf for the HDTV channel should be
Mediacorp HD1:610000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE:33:97:8

However, using MPlayer to play dvb directly results in no detecting the H264 encoding correctly.
There are 2 workarounds

1. Use GnuTV to stream out and play via MPlayer.
'>gnutv -channels channels.conf -out udp 127.0.0.1 5004 'Mediacorp HD1'
'>mplayer udp://127.0.0.1:5004 -cache 60000'

2. Change the vid to 8192. That is:
Mediacorp HD1:610000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE:8192:97:8

With this config, the MPlayer version I'm using - MPlayer dev-SVN-r19355-4.1.0, is able to decode the H264 video and the a52 audio.
The only issue is that the H264 decoder seems not to be fast enough on my machine, resulting in patches and unsteady video.
