Verbatim BD-R Blu-ray 25GB DataLifePlus 16x White Inkjet Hub Printable Discs (50-Pack Spindle)

This would be a matt finish on the top.

The pack that I have is listed as "DataLifePlus." There is no "Q." I don't know the difference. Nor do I know if it's LTH or HTL or even if those designations apply to CDs or BDs. But most name brand disc makers use the better one. I believe that the designation (LTH or HTL) is usually listed if it's the less desirable one and is seldom listed if it's the higher quality one. The fact that it's DataLifePlus indicates it's the longer lived designation. Sorry I can't help you more.

yes.DataLife Plus have been proven the best for DVD-R, DVD-RW, DVD-DL, and BD-R, so I'm sure if you find them in BD-RE they're probably better than what anyone else has..Verbatim just uses better materials for these.

HTL is the original BluRay standard which use longer-lasting inorganic dyes. LTH is a later attempt to use a process similar to CD-R and DVD-R technology which uses an organic dye which is more sensitive to light and is not as long-lasting. As a result I always purchase HTL but it typically is more expensive. A key goal for the manufacturers, or at least as the hearsay goes, was that LTH allowed them to use existing CD-R and DVD-R production lines and thus reduced capital investments to get to BluRay production. By the way another interesting recent option are M-DISC which use inorganic processes as well but for DVD as well as BluRay but I don't have any direct experience with those disks yet.

I use 25 and 116 as the limits for the print. This will leave about 1 mm border inner and outer.

I don't belive they make a BD+R. DVD+R yes. Either way, it does not matter much to the end user. If you want to know exactly what the plus-minus thing means I suggest doing a quick Google search.Happy Burning!

With regards to 2.5 hours recording on these disc's, I have recorded in excess of 3 to 4 hours with no problems, however I'm using a different editing program, you'll just have to do a test run and possible sacrifice a disc.

This is a single layer blu-ray disc. ALL 25 Gig. blu-ray discs will hold the same amount of video. This amount depends upon how many mega bits per second you feed it. Ten (10) mega bits per second will give you about 3 hrs. and 35 mins. AT BEST. This exact amount will vary according to the software and burner you use. 10 mega bits looks pretty good. 16 will look better but the math will tell you that it will take more space. There are 50 Gig. double layer discs available. Most video cameras will record 28 or more Mega bits /sec. To do better than 16, you will have to get software that will edit and produce this fine a video. Ask the experts at B&H for assistance. Walt C., retired sound recording engineer and video editor.
