Thanks, Andy, this was well more than enough to get me going in the right direction. I quickly narrowed down the date to March 30, for which there were only two changesets for the files you indicated. I quickly inferred that it was this change that broke PVR-350 output on kernel 2.6.23: http://linuxtv.org/hg/v4l-dvb/rev/e66ace4b4a61 v4l2: use old-style i2c API for kernels < 2.6.26 instead of < 2.6.22 Updating to the tip and reverting this changeset (ignoring one harmless reject) got PVR-350 output working again for me. Now, I'm not saying that this is the correct solution. I defer to those with a much better idea of what the general effects of this might be. It could be that my kernel doesn't have the old-style i2c API compiled in, perhaps, which is why it failed in the first place. I'm just guessing and unfortunately my zero megabits-per-second Internet upgrade of late prevents me from checking right now. (The "upgrade" is a joke, in case it's not obvious. I expect the problem to be resolved by this evening, though.) > I'm pretty happy with the AFE and VBI changes in the cx18 driver.

Let me be clear -- I record analog signals from a pair of DTV tuners on a PVR-150 and an HVR-1600. Playback goes through a PVR-350 connected via S-video to the television. Now, the PVR-150 has been giving me stable captions (via sliced VBI) for some time now; and as of March 29, the cx18 driver was mostly working, with some sync issues and occasionally dropped captions. My goal, obviously, is to see that last part working. > The PVR-350 uses a different video decoder from the CX25843, so the > changes in the cx18 driver won't be applicable to making VBI on a > PVR-350 better. I don't mean to be contrary, but the PVR-350 is working -and- I have appear to have stable captions on playback for recordings from both the PVR-150 and the HVR-1600. Do you have any explanation? Thanks again for your help! Best regards, --scott _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
