Can't view java content from remote DVR on a client machine that is behind ISA (on SBS 2003.)

I hava a client who has recently installed Security DVRs on a few of his properties that are several hundred miles apart. One location has SBS 2003 Premium with ISA 2004 installed. The SBS server has 2 nics, one for WAN and one for LAN. When trying to access one of the remote DVRs from a client PC on the SBS domain via IE7 the username and password prompt for the DVR pops up, accepts the credentials, starts loading the familiar java logo where the video should be and then, where the video should be, it's just a blank white square. I have set ISA to allow all outgoing traffic, and even some incoming ports. Other than that I'm not sure what other settings I may have missed. I have been able to successfully connect and view video from other networks, with and without SBS domains with no problem. The only thing I see different at this location is ISA.

The model of the DVR is ARM RDVR8A160G.

You'll probably have to permit ALL incomming traffic from the specific IP address of the remote DVR.  This would need to be configured in much the same way Video Conferencing Software is configured in ISA.

You'll find a decent overview of the issues to consider with regards to TiVo through ISA 2004 here:

and a bit more here:

This is not a Tivo. It s a CCTV Security System with a DVR. Thanks for the links. I created a rule for the DVR's Public IP and now I get this message instead of the login page:
 
 Network Access Message: The page cannot be displayed  
 
 Explanation: There is a problem with the page you are trying to reach and it cannot be displayed.

Try the following:
Refresh page: Search for the page again by clicking the Refresh button. The timeout may have occurred due to Internet congestion.
Check spelling: Check that you typed the Web page address correctly. The address may have been mistyped.
Access from a link: If there is a link to the page you are looking for, try accessing the page from that link.
If you are still not able to view the requested page, try contacting your administrator or Helpdesk.

 
 
 Technical Information (for support personnel)
Error Code: 502 Proxy Error. The host server is unreachable. (10065)
 
I created a network with the DVR's IP, created a new rule in the firewall with the DVR Network as the source and internal as the destination, there was no option to allow all incomming so I allowed all protocols that looked remotely appropriate, and I also set it to only allow ports 1-65000. Did I miss something?

I understand that it's not a TiVo but a DVR is a DVR and the protocols should be about the same.... combined with the port needs of video conferencing.  

"Did I miss something?"
You only made the rule for incomming?  It needs to go both ways.

Created a new rule allowing all outgoing traffic to the specific IP and get the same message.

I wasn't sure if there was a difference between a tivo and my dvr as far as ports being used.

I've opened everything I can think of. Someone suggested reseting the listening port from 80 to something else on the DVR itself. What do you think.

I really don't know at this point... since I've stopped working with ISA Server I can't really test anything.  (I removed ISA from all of my clients SBS's because I found it was usually more trouble than it was worth, and instead have installed SonicWall's -- the next version of SBS isn't going to have ISA anyhow... so I'm just preparing early!)

I was hoping you wouldn't say that. Do you think I can uninstall remotely, or will it nock me off before the process is complete?

It's a pretty tricky uninstall... I'd definitely be leary of doing it remotely if nobody is there to get you reconnected if necessary.
