Well, on my Athlon 64 I still get a crash, but now I can't even go back to the alpha.

The beta crashes, the alpha says it cannot render (like it misses the codec).

Alpha now doesn't work anymore even on my Core 2 Duo, as if the beta version is now preventing a rollback to work (to switch I simply register the other filter, having alpha and beta in two separate folders).

Could someone help me with the debug?
download the following file, unzip it and run the two .bat files.
Feedback the results to me.

You must use the single-care cpu because the decoder crashes on it.

These are on my Athlon64 x2, I assigned only one cpu core to the cmd.exe I usted to start the bat...hope this is what you need. They didnt seem to crash for me either with just double clicking (fps number higher though).

I can test on Athlon64 x2/Sempron/Atom/Core Duo if you need...but not before tonight.

Just FYI: Running the batch files produces multiple times produces variable FPS/counters results. Also, that elementary stream is not being decoded properly by DiAVC when using Elecard demuxer (no .h264 file is, really). Not sure if it's the demuxer's fault, but CoreAVC and DivX works fine with Elecard.

The decoder is correct and doesn't crash on the bitstream, that means the filter is with some problems. Thank you very much.
This is a mbaff bitstream and I use it as a conformance verification. I compared the result gotten by my decoder and jm, it is exactly equal. How you get "that stream is not decoded properly by DiAVC"?

I mean I'm getting this kind of output:
http://i45.tinypic.com/2db8jyc.png

Also the video freezes and stutters. I'm using Elecard demuxer. It may be the demuxer's incompatibility but other AVC decoders give proper output with Elecard.

Thank you very much! I found that only the PentiumM and athlon64 got crashing.

Another test for more crash information.

Only pentiumM and athlon64 cpu are needed because the decoder only crashes the two cpu.

With the Beta release I have a strange problem: The video is jumping back and forth like crazy

I went back to the Alpha (2009-12-14) and problem is gone...
