    UDF image size vs file size

    I'm burning DVD/DVD DL discs using UDF and I'd like to max out the disc with recovery data using Reed-Solomon error correction. I wanted to program a disc calulator that could take the file size and compute the image size and determine how many bytes I can allocate for the recovery data. (yes, I'm that bored that I truely want to max out the disc, and not just leave a 2mb cushion space). So my question is does anyone know how to compute the image size based off the file size, or point me to where I can read how do it? Thanks... file size sectors [3 files] data 4,699,950,140 2,294,899 image 4,700,504,064 2,295,168 difference of 553,924 269 ------------ data 6,421,575 3,137 image 6,979,584 3,408 difference of 558,924 271 ============ [1 file] data 4,696,665,772 2,293,294 image 4,697,227,264 2,293,568 differnce of 561,492 274

    Automatic Write Speed

    I've read the guide... How to use the 'Automatic Write Speed' feature http://forum.imgburn.com/index.php?showtopic=4249 What I want to do is to limit the write speed to 2.4x for disc id MKM-001-00 and to 4x for anything else. Problem is it looks like imgburn wants you to explicitly spell out each 'other' disc id. Is there any way to just say if using this device use 4x, unless disc id is MKM-001-00 in which case use 2.4x ? thanks for a great product.

    drive problem

    Thanks, I guess I'm overly paranoid I always thought tdk was good media, but i guess i'll stick to TY or Verbatim, altho I've had playback issues in my laptop drive with Verbatim's. Anyways heres a new speed graph/pipo test, i burned at 4x, much better then before but still not great. cloud.prohosting.com/rqvcd/woah4.png cloud.prohosting.com/rqvcd/woah4a.png

    drive problem

    Not really an imgburn problem but I just got a new nec 3550. Came with 1.05 firmware, I went ahead and put 1.06 on it. Problem is the buffer says 100%, but the device buffer is usually around 96% and about every 60 seconds or so the device buffer drops down to 0-20%, every 60 seconds and the buffer never goes down at all. Obviously it slows down the write speed a little. I've used verify on a bunch of the disc's and they're all fine. The images are on a raptor 10k rpm drive... the burner shares an ide channel with another dvd drive but its not in use during the burn. No cpu/io intensive apps running, ie virus scan, prime searching etc.... PC is an amd 3200+ with 1gb of ram.. so it?s definitely not slow. I'm wondering if this is normal or if maybe I got a defective drive?
