    Hello forum, I'm trying to capture VHS/Video8/Hi8 with AmaRecTV 3.10 but I think I have problems.

    When I capture I always have 7/8/9/12 Drops in the start of the capture. Example: Drop[ 12, (+)0, (-)0] and few minutes later Drop[ 12, (+)1, (-)0]

    The +1 is increasing and in an hour of recording it can reach +23 (for example).

    I configured same as here: https://kb.speeddemosarchive.com/Amarectv_configuration

    In the log.txt I have this:

    VT=00:13:16.326s(23862f), Cap=24683f( 12D), Enc= 5.044ms, Siz= 263KB( 39%)KEY, Drp=0, (+)23, (-)0, Buf= 1, o

    This is my computer:

    Where is the problem? Thanks to all!

  2. I'm guessing the 40Gb IDE system hdd? Does your mobo only have one SATA port? Buy a bigger, faster SATA drive, clone your OS system across onto it? (Unless you have access to a PC with a newer version of Windows to use a newer version of a cloning util, you may well have to back up the old hdd and restore onto the new, but as you already have the 1Tb capture hdd . . . and 40Gb isn't very big . . .)

    Or it could be the just 1Gb of RAM. Even for XP 1Gb was often a major cause of bottlenecks.

    My mobo have two IDE and two SATA. I will try now only 1GB and I will tell you news. Thanks!

    I discovered that with a crappy capture device I have 0 drop, but with ATI 600 and the clone I have that problems. What must be the problem? I use the latest driver for that grabber. Does it have to do with the fact that you are using an ATI 9250 graphics card?

    I'm biased through recent experience with Blackmagic Shuttles and USB 3.0 chipsets.

    I had similar problems when using ASMedia or any brand of USB 3.0 port chipset "except" the uPD NEC 720200 USB chip.

    The USB connection has a lot of problems, "especially" with USB 3.0

    USB 2.0 was a very rigid specification, chip makers and motherboard makers were literally "forced" to participate in compatibility "bake off events" before they could label their products USB 2.0 and could sell them to consumers.

    USB 3.0 manufacturers fought back.. and removed the "must comply with standards" edict.. it was a marketing and sales "disaster" of EPIC proportions.

    (Most) motherboard manufacturers simply removed all documentation about their USB 3.0 ports and declined any technical inquiries about them.

    HP and Dell "rigidly" paid extra money to buy motherboards with (one) USB 2.0 chip on one port.. so they would not get sued into oblivion. all other ports were no-name USB 3.0 ports

    The problem is in the design of the cheap USB 3.0 ports.

    NEC was the champion of USB 2.0 chipset design, first to market, and very compliant. When they made their USB 3.0 chips.. they did not sell well because.. they "were not cheap". So they partnered with Apple, Sonnet and very high end PCI/PCIe companies to make add-on cards with the uPD 720200 chip .. they are very compliant, compatible, industrial grade.

    .. and.. they don't drop frames

    There is a myth they are hard to find.. not true.. but they are not cheap.

    The cards today cost around $30 for a two port uPD 720200 based card.

    Now the high speeds involved mean sometimes you can get one port that works fine.. but another does not.. so be sure to not trust only one port.. and switch around to find one that does not drop frames.

    On a bad port.. frame drops are fairly common.

    Using AMARec 3.10 (on a good port) .. absolutely "Zero" frames should be dropped.

    Its probably not a capture device problem.

    Its probably a sketchy USB chipset, or bad USB port.. in manufacturing even if you have a great USB chip a bad solder job.. or weak PC board trace can cause problems.
