szap -r does not route video to dvr, only audio is delivered. This applies to linuxtv-dvb-apps-1.1.0_p20060423.ebuild. Workaround: use linuxtv-dvb-apps-1.1.0_p20050702.ebuild. There szap works as it should.
I reproduced the bug here. Does it work for you with linuxtv-dvb-apps-1.1.1.20060917 ? Then I try to get it stable as soon as possible.
(In reply to comment #1) Yes, it works with linuxtv-dvb-apps-1.1.1.20060917
Marked working version stable and removed buggy ones.
