New alpha dongle Dec 28.

Lindsay,

Since none of these are the dead keyboard problem and I don't think they are necessarily mvpmc related either I don't see it as bad as it sounds

1. for the Internet radio problems, I don't see any attempt to contact mvpmc on the media stream [7] My first instinct is the recording service isn't able to get the data to create the temp file. however if you look at the logs I notice the Shoutcast text data logged. I don't know how the Shoutcast parser works, but I now am speculating that this is a problem with this stream..

2. Live starts really breaks starting at 17:17:15.229 I don't know if the client or server is at fault, but there definitely is a missing end of stream from the server for Flight 29 which for now will lock mvpmc if a new media stream starts.

3. Here is one log snippet for sub to review

2008-01-08 17:45:13.738 VERBOSE [7] Request completed. 200000 bytes sent
2008-01-08 17:45:13.740 VERBOSE [6] MVP data read: 1 (9)
2008-01-08 17:45:13.740 VERBOSE [6] MVP request processed

2008-01-08 17:45:13.740 VERBOSE [6] Got ACK

a. mvpmc would have send a request to read right here on the media stream. There is no blocking in the mvpmc code and the pings are working fine so think it networking is working

b. Interesting

c. Finally the data gets read. The fact that the timeout issue often seems to be thirty seconds might be relevant to Vista problems

4. Sub, there's another new log message that I'd like explained if you have time.

VERBOSE [7] MVP media connection recycle requested

Martin, I have been experimenting a bit since my last problem report. I am now of the opinion that Vista owners should disable the TCP auto tuning. I think the data stream to the MVP was not being handled properly. The sure sign of this was the micro pauses I was getting in Live TV. These seem to have gone now and I can't get the channel changes to mess up and the Net Radio station changes seem reliable as well.

I can't be sure just yet that my system is completely cured but I can live in hope! But since there are no disadvantages to switching off the auto tuning, we may as well do it. There are many reports of problems with routers as well.

I have switched both auto tuning and rss off. I think both are necessary for me.

In case others are interested, at the command prompt, with admin privileges, execute these commands.

netsh interface tcp set global autotuninglevel=disabled
netsh interface tcp set global rss=disabled

The first cmd can be reversed by replacing disabled with normal. The second, use enabled instead of disabled.

This cmd displays the status

netsh interface tcp show global

Interested in feedback, folks.
