I have just loaded Air Video and am extremely impressed - it works great under Win XP. I tried the server under Windows 7 however and I get a STOP error in tcpip.sys as soon as I start to stream a video. Is there plans for a Win7 compatible release soon ?

Works for me under Win7 RC 32bit.

We've number of users that have Windows 7 installed and haven't had report like this. I will try to reproduce the problem later today or tomorrow.

What is the nature of this error? Is it a BSOD like error where the computer crashes? Because if so it's most likely problem in network adapter driver.

Sorry, forgot to mention, I'm running Win 7 RTM 64-bit on an Intel i7-920. Could be to do with the drivers and I'm checking for an update in that regard. I have a Gigabyte EX58-UD5 motherboard with everything integrated. There's a Windows Update that wants to downgrade my network drivers from NDIS 6.20 to 6.0 (don't know why) but I haven't installed that so I'm currently running the NDIS 6.20 driver that installs from Win 7.

This is definately a BSOD - didn't catch the numbers though.

Air Video is an user space program. If running it causes BSOD the problem is likely either in drivers (network drivers probably in this case) or faulty hardware.

Yeah dude I would imagine that since Airvideo's compression will start to push your CPU if you had hardware issues it would lead to a BSOD. Try a prime95 test and see what happens.

Getting tons of BSODs on air video after recently updating to 2.4.2 server.
Never had any problems before...
Windows 7 x64 OS, q6600 cpu, 4gb ram

I opened the minidump in the microsoft debugger:

APC_INDEX_MISMATCH (1)
This is a kernel internal error. The most common reason to see this
bugcheck is when a filesystem or a driver has a mismatched number of
calls to disable and re-enable APCs. The key data item is the
Thread->KernelApcDisable field. A negative value indicates that a driver
has disabled APC calls without re-enabling them. A positive value indicates
that the reverse is true. This check is made on exit from a system call.
Arguments:
Arg1: 0000000077500eba, address of system function (system call)
Arg2: 0000000000000000, Thread->ApcStateIndex << 8 | Previous ApcStateIndex

Also got a couple of tcpip.sys failures as well (As indicated above) -- I'm going through all the saved dumps to see how many of them contain airvideo in the backtrace.

Alright...2.4.3 is out, I'm going to try that, hopefully it fixes it.

I'm afraid Air Video Server itself can not bring entire Windows down. If that happens it's either a bug in a driver or an overheating problem (i.e. during live conversion).

Air Video Server runs in user space. If there is a bug in it, Windows will terminate the server.
