Here's the Netflix fix (from Rev) if anyone wants to edit their build.prop file (in /System):
The line that needs to be commented out is at the end of the build.prop file...you can put a # in front of it as below to comment it out.
...
ro.config.alarm_alert=Alarm_Beep_03.ogg
ro.modversion=CyanogenMod-7.1.0-RC0-DROID2-KANG
# ro.kernel.android.checkjni=1
ro.setupwizard.mode=OPTIONAL
dalvik.vm.dexopt-flags=m=y
net.bt.name=Android
dalvik.vm.stack-trace-file=/data/anr/traces.txt
Worked perfectly, 1.3 netflix now works.
I've attached a totally stock, CM7GB build.prop file with that one edit made. You can replace your existing stock build.prop file with it if you want to skip editing the file yourself. Be sure to set permissions/ownership on the file the same as the existing build.prop (which you should rename). Then reboot.
The file is named as a .zip file but it's not, simply delete the .d2.zip at the end, it's a simple build.prop text file. I did this and Netflix 1.3 plays perfectly fine again.
If you're running Jake's mods then you either need to edit your own file, as this build.prop has none of his customizations.
If none of this makes sense to you, then don't do it.
