My problem was/is that the PVR-150 fails to sync to the frequency of the OSD screen (the picture you see when the VCR is on but did not yet press the Play button) with the ivtv driver but not under Windows. What is even more strange, the recordings made with the tape playing are OK though. We had a discussion with Andy and he suggested to run a series of tests but it did not improve the situation. I think your problem is maybe related to mine and both are related to the cx2584(0-3) module. Perhaps a bit/byte needs to be changed in one of its registers? Recently I read on this list there are forthcoming changes affecting this module, I will redo some tests when the change will be incorporated into the v4l repository. Levente PS: On a side note, last December Alexander Pipelka was trying to encode without B-frames with his PVR-150 and he failed (as well as me). Here again the cx25840 was possibly the culprit. _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
