The flexibility argument makes sense. By the way, what sort of bitrates and options would work if I wanted to make a 720p version that fits on a DVD-9 as a “fake” (AVCHD) Bluray. I tried doing a 2 pass encode through Handbrake at 8900 kbps and while the resulting file looks great (certainly better than HD from Netflix), the resulting data doesn’t fit on a DVD after being run through tsmuxer. How low can you go before things start looking like crap? Is it possible to go down to 4000 or so and fit on a DVD-5? I’ve currently just burned the raw MKV of my 720p encode to a DL DVD, but I understand that an AVCHD-format disc might have better compatibility with hardware players.
