64 * - check PCR frequency requirement
66 * - check PCR/PCR "soft"
67 * - check if "registration" descriptor : "AC-3" should be a program
68 * descriptor or an es one. (xine want an es one)
70 * - remove creation of PAT/PMT without dvbpsi
73 * - subtitle support is far from perfect. I expect some subtitles drop
