alpha? amd64? ia64? sparc? :-)

Those errors don't make sense on their own. I'm guessing that there were
errors before them...

Not surprising since I added a bit to that code not that long ago.

That change, together with any change which uses that constant, is BROKEN. It
will cause failures when playing back TS files, recorded via xine-lib's DVB
plugin, which contain MPEG2 video.

(xine-lib's TS demuxer is a bit broken here in that no descriptor tag was
found so it's falling back on using a value from a different source as if it
were the descriptor tag. 0xE0 only indicates that it's a video stream.)

Detection-by-content for the 'default' case for the video format detection
code (around line 800) is what's needed. (Patches which implement this and
this alone will be considered.)

You've either omitted a comma or added the extra line in the wrong place. :-)

[snip fallout from that error]

Not surprising. It's mispatched.
