At first BD5 and BD9 may sound like a boring topic, but it is important if you shoot and distribute HD. WHY? Because both allow you to burn HD material to standard SL and DL DVDs. Wait, isn’t DVD a SD format? Not exactly; you see the BD5 and BD9 may be on a DVD, but it’s in the Blu-ray format. So this plays back on a Blu-ray player in HD. Thus, any computer with a DVD Burner and the right software can burn HD Disks. So much for the good news. The bad news is that a SL 4.7 GB DVD can only hold about 20 minutes at the maximum data rate of 30 Mbps. Slow the data rate down to 20 Mbps and you get about 30 minutes. Use a DL 8.5 GB DVD and the times range from about 35 minutes at 30 Mbps to 60 minutes at 18 Mbps. OK, so it’s not a full length movie, but it could be enough for some jobs and even a wedding skateboard video. 
Why BD5 & BD9 Is Important To HD Users
On vient de rentrer de Toulouse.
Un bain de bonheur pendant dix jours. Du beau temps, des restaurants, des salades, du vélos, de l’amour.
J’ai eu quelques nouvelles idées pour la soupe.
Utiliser des déguisements et des grosses lettres en carton.
Coca la journée, Montbazillac la nuit, vive les vacances.
