Quick data points with Finnish YLE DVB subtitles, using a dxr3:
1.7.22: everything works (never tried versions between here, because I was stuck with a 2.6 kernel back then) 1.7.25: subtitles are almost black and thus illegible 1.7.26: same thing 1.7.27: colours OK, but during live programming, maybe one of every 20 subtitles shows at all, and are about half the correct size. Same thing when viewing recordings made with this version - when I replay old recordings, all subtitles seem to get displayed.
vdr-dxr3-plugin version 0.2.13 from here: http://projects.vdr-developer.org/projects/plg-dxr3/files
em8300 drivers from here (cloned on March 17th, I think): hg clone http://dxr3.hg.sourceforge.net:8000/hgroot/dxr3/em8300 dxr3
System Ubuntu Oneiric, kernel 3.0.0-17 from Ubuntu sources (but recompiled by myself, because those nice folks at Ubuntu had to turn OSS support off in the kernel, preventing the em8300 drivers from working)
