I don't remember mentioning it, but it is always a rather informative

As you subtly hint at below, there is a set of w32codecs for PowerPC, that
is obviously less complete than its i386 counterpart; however, nobody has
packaged that set for Ubuntu TMK. When I checked, it was missing the RV4
codec even though it's in the RealPlayer 10 for PowerPC Linux
installation. The only reason RealPlayer 10 for PowerPC Linux is not on
their downloads page is that it's based on the open-source Helix Player,
even the open-source form of which refuses to work on PowerPC. Crap code
is not limited to proprietary software.

The problems you have with 6.10 may very well be present on i386 also.

I think that of all the .swf's I tried with gnash, only one worked, and

I think it's also worth mentioning here that neither Windows Media Player
10 nor 11 files will ever play on OS X. Those versions do not introduce
anything codec-wise, only DRM.

Pedanticity time: According to the CodeWeavers booth at MacWorld,
"CrossOver Office" no longer exists.
