I'm new here, but may have a problem posted to by some users of similar DVRs. My DVR is a "Gadspot GS2002", which uses an activex control from "zhuhai raysharp technology", the activex control is named dvrocx.ocx. The DVR manual and DVR-based UI look very similar to qsee, avtech, and a couple other DVRs I've seen so I suspect it is of similar lineage. It uses an h264 codec. My problem: I have configured the DVR, and have it actively working. I can use it fine locally on an attached monitor. Remotely, on the local area network, I can log in, but I get no picture from cameras (it actually shows a dark grey screen) either live or replay. I get no errors, just no video. The thing is that it does work on some machines and not on others (worked on a vista x64 machine, a vista x86 machine and a win7 x86 machine, failed on 6 others). Because of this, I know it is not simply a malfunctioning or misconfigured DVR or network problem. I've been trying to troubleshoot this with the vendor for over 5 weeks now, including multiple rdp (remote desktop) sessions with their tech support and engineering. The first one they disregarded because it was in a VM, so I set up a dedicated machine for them to do whatever they wanted on, but they've not been able to get it working there either. I really suspect there is a problem with their dvrocx installer assuming some dependency on the machine which is not there, but they can't seem to figure it out. Does anyone have any wisdom with these, or am I getting what I deserve for buying a sub $200 DVR?

I think the software is garbage, it isn't any "server cpu" issue. I've done various testing on many machines in my household, 32 and 64-bit OS, XP, Server 2003, Windows 7, Vista, Server 2008, Server2008 R2. It works on some machines, it doesn't on others. Reinstalling the OS on one machine cleaned up the problem with no hardware changes. On another VM, it worked for a while and then stopped. I usually don't bother accessing my dvr (gadspot gs2002) over the network because the software is garbage. dvrocx.ocx, netviewer is a host application for it to use something other than IE, but ultimately it is the same thing. I wish I had some reputable third party program to access the video stream.

What brand/model is your DVR? Do you use the same dvrocx.ocx control?

Oh, I am able to install the activeX control, and it is able to communicate with the dvr and all. It is an issue with the activex rendering the video on various machines. The vendor's tech support had a tough time getting past general activeX and site permission troubleshooting. One other thing - their tech support also gave me a "d9 viewer" which accesses it without the browser (I don't know if it is using the activex control or is a different implementation of it), but it doesn't work either.
