[mythtvnz] H.264 scan support for dvb-utils and w_scan

[Steven Ellis]

At present the tools scan/dvbscan and w_scan assume that the video has a
stream type of 0x01 or 0x02. This means that they aren't detecting the
vPID for the H.264 DTT transmissions as they are using stream type 0x1b.

For dvb-utils the following diff will provide H.264 scan support

--- linuxtv-dvb-apps-1.1.1.orig/util/scan/scan.c
+++ linuxtv-dvb-apps-1.1.1/util/scan/scan.c

elementary_pid);
                        if (s->video_pid == 0)
                                s->video_pid = elementary_pid;
 

In the case of the tool w_scan a similar line is needed in the function
parse_pmt.
