Yeah, I agree with LUK. Splitting the image wouldn't have made any difference. It may have been just a bad blank in the box, like you said. It happens. I came across a bad DVD+R DL recently. My 2nd attempt to burn it and all subsequent DVD+R DL have burned fine.
BTW, as a general rule of thumb, I try burning a failed image burn 3 times in a row to see if it's just a bad blank disc or not. After 3 discs, I'm relatively sure it's probably not the discs, unless it's a brand new stack/manufacture. After 3 fails in a row, I'm more inclined to blame the drive for the problem. Or could be a problem with the image. It happens, but rarely.
As for the Pioneer BD I have, mine is the BDR-209M, aka the BDR-2209. The only difference between mine and the BDR-209DBK is mine supports writing to BD XL media and M-Disc media. If you never intend on writing to either of these types of discs, you can save a little money and go for the BDR-209.
I've never heard of the BDR-S09XLT, so, I looked it up. It seems to be an older Pioneer model. I've heard of the BDR-S08XLT, but that's older than the 2209. It seems the XLT was an older generation of the 2209. Pioneer's website only lists they manufacture the 209 models. There are no XLT's anymore. You can still find XLT's online, but most of the prices I've seen are near $200, except for $90 from Groove Inc. However, the 2209 will also run you $90, so you're better off buying the newer drive. It's firmware was last updated a year ago whereas the BDR-S08XLT firmware was last updated 4 years ago.
Now, there is a newer Pioneer BD model out there. It's a 4K Blu-Ray drive. However, there's no firmware update for it yet so it's so new it may be TOO new to recommend. Plus, it's nearly $25 more than the 2209. If you never intend on viewing 4K Blu-Ray, then there's probably no real need to get that one.
