1.How is possiable to burn nine hours of High-Definition video on a write-once BD-R disc or a rewritable BD-RE disc?
2. and doe's this include WTV and MKV files? or what type of HD video files is Liton referring to? I'm thinking the MKV files are mearsured in size rather than time so this nine hour would'nt apply to MKVs.
3.also these burnt BD-R discs will they playback on differnt BD players?
4.I'm assumming the slowest burn time is used kindof like extended long play? doe's this type of recording effect the quaility?
5.I'm not farmiaril w/ LITE-ON
are they known for good customer service?
usalley a co. w/out a 800 surport phone # indicates lower service.
just to clairify writer, burner or (copy to) are the same?
Player and reader are the same?
Thanks STB
Audit13 has already answered these questions but I will try to expand a little bit.
1. "High-definition" or HDTV primarily takes into account the number of lines that make up the picture 720p, 1080i and 1080p are all considered "high-definition" for comparison, 480i is considered "standard definition" and it has been around since the inception of TV back in the 30s. There is also 480p which is called Enhanced Definition or EDTV. There are other factors like aspect ratio 16x9 for high-def vs 4x3 for standard def. What it DOESN'T take into account is bit-rate which is the main determining factor of quality and thus file-size. I can take a 2-hr 720p video and encode it with a low bit-rate like 4MBits/Sec and the file size would be less 5GB at the same time I can take the same 2-hr movie 1080p movie and encode it a very high bit-rate like 20MBits/s and the file size would be around 20GB. Both would be considered "high-def" but the 1080p movie would be of much higher quality. So if I encode at 720p resolution and 4MBits/s I can easily fit 9 hours of video on a BD disc.
2. WTV is a container developed by Microsoft and only used by Media Center. Here in the US it contains MPEG2 encoded files from cable TV. MPEG2 is not a very efficient encoder especially when compared to h264 which is much more efficient meaning quality is retained much more at lower bit rates. Do some reading about mpeg2 vs h264 encoded files.
3. What determines whether a BD disc will play in a BD player is how the files are written/burned onto the disc. Unless specifically stated that the BD player supports mkv files, every BD player expect the discs to be in the BD structure made up of specific folders and specific files (aka AVCHD). Kind like a DVD player expects to see DVD structure which is made up of a VIDEO_TS folder containing VOB files which are nothing more than MPEG2 encoded files but guess what, if you write/burn a MPEG2 file onto a DVD and stick it in a DVD player, it won't play because it is not in the correct structure.
4. Burning times have nothing to do with quality. Burning or writing to a disc is just transferring the digital data from your hard drive to the disc. The quality was pre-determined when the video file was encoded. You are thinking in analog and not digital. Once the video file is created the quality is set. Where you play it from be it from a hard drive or a dvd disc or a BD disc makes absolutely no difference. It's like taking a photograph with a digital camera. The quality is determined when the picture is taken by how you set the camera. It doesn't make any difference where you store that digital photo once it is taken. You can put it on hard drive or a flash drive or a dvd disc or any other medium you can think of. When you view that picture, it will look the same.
5. Lite-on is a very well respected manufacturer for BD/DVD burners/writers. I have had several of their products and I have never had to call them so I can't speak for their support. Usually with these types of devices it will either work or it will fail very quickly in which case you just return it from the place where you purchased it for a replacement.
Burners is just another term for a writer. It comes from the action the device uses (a laser) to burn or etch a very small pit to signify a bit onto the surface of the disc.
Don't take this the wrong way but this is a fairly advanced topic and based on your questions you lack the basic knowledge of how digital video and audio is encoded and how different encoding, containers, and file structure affects what you do. Unless you spend some time reading and become more knowledgeable about these concepts you will find it very frustrating.
