MediaMVP with MVPMC hangs after some time

[pz1]

Martin: I again tried MVPMC (30-9-2008 version) but am still getting the lost keypresses, no disconnects: the keypresses just disappear. Only switching theMessage to Martin MVP off and on restores normal functionality. Is there a later version which does not exhibit this problem?

I to do notice loosing keypresses. I have the impression that if I push more firmly on the Hauppauge remote, I have less losses.

The main problem is that during video the remote key messages stop flowing between mvpmc and GBPVR. Repeated tests with client side telnet captures show that mvpmc is seeing the keystrokes and sending it to the tcp socket, but there is blocking going on somewhere. The Hauppauge protocol doesn't allow a method to reopen the socket in this situation or I would do that.

@OrakelJos there is no version of mvpmc that fixes this and I am not going to followup on it. Your comment that the Hauppauge dongle restarting during video play would be exactly what I'd expect when the heartbeat responses stop. You can try some other values on the tcp window with the --em-rtwin command line option, the default is 8192 because some GBPVR users told it worked best. I found a smaller value --em-rtwin 4096 has fewer TCP errors at the expensive of reduced preformance. I have no idea of the impact on the keystroke problem or the best values to try.

You are right with your comment to Pieter. I am using a Harmony remote and have the same problem. The MVP receives them but they are just lost on the way to the server.
Will try out your suggestion but if it remains a dead end I will switch over to the NMT A-110. My son just bought it last week and got it working with GBPVR so this is probably the way to go. In The Netherlands they cost € 299 vs. $ 215 (= € 150) in the US so double the price here :mad:

I feel the pain here in Canada, too. The PCH is about 30% more expensive now then when I first bought mine and we pay international shipping so it does make a tough choice and which is why I don't push it as a solution, even with its technical superiority. However to be fair the A110 is overkill for most GBPVR user's needs and for me it doesn't justify $75 difference from the A100.

I have switched off ALL 5 TCP/IP offloading options on my Intel 82566DC Gigabit controller. Since that time (2 days) I have no disconnects
Will now enable those options one by one again to see which one is causing the problem. I know that is is not the TCP Segmentation Offload since I tried that one earlier so it must be one of the other 4 remaining. It seems to be a similair problem as some users have reported on the nVidia NIC.
Will be continued.....

Have updated the Intel 82566DC driver to version 9.12.36 from 4 dec. 2008 which was released a week ago. Offload options are still disabled. No restarts anymore with the Hauppauge AND mvpmc dongles
Will continue with this setup for a couple of days and then start to enable the offload options one by one.

[OrakelJos]

Have enabled the first 3 offline options again: offload receive and transmit IP checksum and receive TCP checksum. Is still working without problems. Will now add "offload Transmit TCP checksum" and see what happens

[OrakelJos]

Enabling Offload Transmit TCP checksum or Offload TCP Segmentation is almost immediately causing connection problems with this particulair Intel network card. So those two settings were the cause of all my problems :mad:
The other three offload settings can remain enabled (see my previous posting).
I hope that other users can benefit from my experience
Martin: will order a Popcorn tomorrow

That fix worked for me and saved me a ton of time troubleshooting. Thanks!
