Direct2PC Problem on one computer

Check system, applications, etc logs in Win7; different codecs on the computers perhaps ?

Nothing in the logs, no error messages at the times I tried this. Codecs would effect playback. Problem is just that computer doesn't load the playlist from the DVR. I just checked on the DVR under Photo sharing and it sees my desktop computer (of course that is the other direction of data). So I have verified several ways that they are connected and can talk to each other (ping, etc).

Well, then try dbgview, spy++ or other debugging tools...

Do you have vmware installed? It will cause problems.

I did have VMware installed but I was aware of the issue. First I disabled its network connections, didn't work. Then I just uninstalled it, didn't work. I may search for any remaining files or registry entries depending on how my clean install test goes.

I installed Directv2PC on another computer I have and it worked.

I put in a spare hard disk and restored it to my configuration one year ago, didn't work. That did have VMware on it however.

Now I am go to just install a clean copy of windows on that disk and see what happens. Will post back.

Something really weird here. First a summary.
Computer 1 has problem. Directv2PC runs but can't load playlist.
Computer 2, it works.
Just installed on Computer 3, it works.
So I go back to computer 1 and on a spare drive do a clean install of Windows 7. Directv2Pc runs, loads the playlist, plays programs but screen is green, audio plays.
Go back to computer 3 and it now it has the green screen. Worked one hour ago.
Computer 2 still works.

In all cases the network communications are OK both ways. I tried with only one computer on (other 2 off) in each case, no change. All 3 computers are hard wired to router, all have Intel Core CPUs.

I am beginning to think Directv2PC is just flaky, not worth the effort. Problem could also be in the HR34 software which is still "immature". Called Directv tech support, no help.
