Thanks Carsten. Interesting bit you’ve found.

I will delete Skype and see if that has anything to do with the problem.

Yes, I have set the audio to internal and can get the VTR Xchange to work that way. It’s when I try to use the audio from the IO box that doesn’t work.

Yes, I don’t think the “HPplugin” is from Hewlett Packard.

Good tips.

Best,
Park

Still stumped.

Can’t find the mysterious “HPplugin”. Is it really something from HP? Or something else. I think I have deleted all the HP files.

From the system log when I try to use the AJA IO.:

Jul 21 18:39:33 ParkMBP [0x0-0xc00c].com.apple.systemuiserver[141]: HPPlugIn::StreamGetProperty: unknown stream

Thanks, Gary.

I have deleted all the HP printer and such in the computer. I did have an old laser printed once hooked up via USB and an adapter to go to parallel interface but haven’t used that in a few years.

Yes, I do think this is a software conflict. I did make a new user before deleting all the HP stuff and saw no change but will try that again.

I don’t have anything HP connected.

Thanks for your note but it is not the drive. AJA was not concerned when I was using the internal for testing.

I did hook a OWC 7200 RPM drive via USB and no change. It performed exactly as the internal with DV and DVCPRO50.

If the audio device is set for ProIO, it will not capture with VTR Xchange. If I set the audio device for built-in microphone or built-in input, it works. If it is set for ProIO and I turn off the audio, it captures. It will not capture with audio set for ProIO.

I was dropping frames on the uncompressed test. It was only to test the capture of audio and video. It did not matter if I lost frames on this type of test.

With FCP, it will not capture no matter the audio settings.

Yes, I know I need an external. But if I can’t capture, it doesn’t much matter!

My MBP does have a FW 800 but I believe it is on the same bus as the FW 400 and so I can’t use an external when using the AJA IO.

Yes, movie. If you remember from my original post, I said I can capture video in Xchange if I don’t include the audio from the IO.

It is the large rack mount IO and I also have the IO LA analog box. AJA has sent me the large IO and another IO LA. Same results on all hardware boxes. Yes, I am using the correct software for each box. I use the AJA uninstall before loading different software. I also did en erase and restore through Time Machine and did a combo reinstall of the OS.

Best,
Park

Hi Jeremy,

I am using a 2.2 Gig MacBook Pro Core 2 Duo with 2 GB RAM. The name must have come over when I migrated from my old PowerBook two years ago.

I don’t believe I had both FCP and Xchange opened at the same time since I thought that wold conflict but I will delete all prefs in FCP, AJA and QT just to be sure.

I have tried many different AJA formats from uncompressed to DV, all in SD. I am recording to my internal now and will get an ExpressCard to FW 800 if I can get this to work. Nothing but the IO is connected to the FW bus. I have tried the IO LA and the large IO on two different computers. The other is that PowerBook G4 with 10.4.11. Same results Feeding color bars from a Grass sync generator.

Best,
Park

Hi Bryce,

Nice to hear from you. Glad to hear Peter is going well. Talented guy. California seems to attract the best and the brightest!

Best wishes,

Best,

Take a +4 dbm audio tone. It will read “0” on a Digi Beta AND an analog Beta. The Digi Beta is -20 DBfs. That is an exact match for 0 VU on the analog Beta.

It does work for analog. To be clear, we should use the notation “DBfs” (full scale) when referring to digital levels.

On 1″ Type “C”, timecode is on audio channel three. On standard Betacam, TC is on channel three.

In the service manual for Digital Betacam,for example, the timecode audio track is just called “time code”. It is not given a number.
