Do the following work?
ffmpeg -i test2.wtv -sn -qscale 5 out1.wtv
ffmpeg -i test2.wtv -sn -vcodec copy out2.wtv
ffmpeg -i test2.wtv -sn -qscale 5 -acodec ac3 -ab 256k out3.wtv

And for those outX.wtv that work, please try:
ffmpeg -i outX.wtv -vcodec copy -acodec copy out.wtv

ffmpeg -i test2.wtv -sn -qscale 5 out1.wtv
ffmpeg -i test2.wtv -sn -vcodec copy out2.wtv

This should be:
ffmpeg -i test2.wtv -sn -ac 2 -qscale 5 out1.wtv
ffmpeg -i test2.wtv -sn -ac 2 -vcodec copy out2.wtv

I ran all three conversions as directed. Each resulted in a file that would not render in MPC-HC, WMP, Media Center or Graphedt.

If needed I can provide some sample content...

So far I've got two source files that fail, and one brief one that works well. I've not done an exhaustive look into what is and is not failing. So far, one HD and one SD stream fail, one SD stream works.

[Carl Eugen Hoyos]

Please provide a sample.

Edit: I've pulled this file from my site...Please ping me if it is needed again.

[pross]

Okay, i can reproduce the error. Looking into it

[Carl Eugen Hoyos]

I tested the following commands with the sample you provided:

ffmpeg -i test1.wtv -sn -ac 2 -qscale 5 out1.wtv
ffmpeg -i test1.wtv -sn -ac 2 -vcodec copy out2.wtv
ffmpeg -i test1.wtv -sn -qscale 5 -acodec ac3 -ab 256k out3.wtv
ffmpeg -i test1.wtv -sn -vcodec copy -acodec copy test.wtv

All four files play fine with WMP12.

Seeking with WMP12 is not possible in all resulting files, is that what you wanted to report?

[Ian Kennedy]

"Seeking with WMP12 is not possible in all resulting files, is that what you wanted to report?"

No. With the build I was using I get unplayable files. It looks like Peter got a repro...

[Carl Eugen Hoyos]

It appears this was fixed since you originally opened the ticket (but before I was able to test).

[Ian Kennedy]

I've verified that I can now convert from WTV->WTV and that (as noted above) seeking is totally borked.

Seeking it broken not just in WMP, but in MC as well. The SBE source is somewhat confused.

[Ian Kennedy]

One more thing: I have another test file that fails to re-mux. However it's a 5GB HD recording. SO things are improved, but not fully fixed.

Command line and complete, uncut console output missing.
