Is it fixed in place or on a sled?

Geometry correction is generally trial and error and will depend on mounting location/lens shift/distance, you will likely need v small deviations from no correction but basically show a grid pattern and get the lines to visually align then measure the boxes to see how different the dimensions are in the middle Vs the extremes and adjust til they are approximately the same size

Then switch on Logging in MC in the hope that the MC Logs will allow Bob, or anyone else, to discover caused MC to crash.

Removed both of the settings files, ran gdb mediacenter34 with the built in browser option and got this:

Bob said the segfaults could because of corrupt settings files. Try what he suggested here: https://yabb.jriver.com/interact/index.php/topic,141310.msg980605.html#msg980605

I have a large text field that would look a lot better if I could search for a character (ex. •) and replace with a hard carriage return using FIND AND REPLACE in JRiver.  This way each variable would be on it's own line:

 Current:
1987/Cassette - Columbia(JCT-33795) [Born to Run] •  1987/CD - Columbia(33795) [Born to Run] •  1989/Cassette - Columbia(6865813T) [Born to Run] •  1990/CD - Legacy / Sony Music Distribution(52859 CK) [Born to Run] •  1992/Mini-Disc - Columbia(33795) [Born to Run] •  1994/CD - Legacy / Master Sound(64406) [Born to Run] •  2000/CD - Sony Music Distribution(CD 80959) [Born to Run]

Would like:
•  1987/Cassette - Columbia(JCT-33795) [Born to Run]
•  1987/CD - Columbia(33795) [Born to Run]
•  1989/Cassette - Columbia(6865813T) [Born to Run]
•  1990/CD - Legacy / Sony Music Distribution(52859 CK) [Born to Run]
•  1992/Mini-Disc - Columbia(33795) [Born to Run]
•  1994/CD - Legacy / Master Sound(64406) [Born to Run]
•  2000/CD - Sony Music Distribution(CD 80959) [Born to Run]

I've tried some special characters but no luck.

Any help would be appreciated

Thanks
Matt

Agree with ET here. Unless Bob can reproduce the crashes it gets hard without the crash dumps.

For good measure you might also enable logging in MC and then reproduce a crash and post the logs here (along with the crash dumps if possible).

Replied earlier agreeing crash dumps are needed and helpful. However, one critical thing I should reinforce is that for many of these there are no crash dumps. The app *instantly* and completely died the moment I clicked in the tree view. No remnants were left to provide. No crash dumps that I'm aware of. No standard Apple "the app crashed report this to Apple" submit screen. It just disappeared from my screen, the DLNA server closed, and that was it.

In that case you may need to post the crash dumps.

Understood. Wanted to at least get the symptom posted, but clearly can't be debugged w/ out some hard data. I did end up doing a complete shut-down, power off, and reboot to see if that alleviated anything. Haven't run it much since original post due to recent travel but will circle back on status.

Thank you!

Whenever you have issues segfaulting on start in a setup that worked previously (same OS, hardware, etc) you might have corrupted settings files.
That can come from interrupting a startup by killing the process and other things.

You can try removing the Settings file(s). You will lose you settings and library. Hopefully you have a backup.
First try just removing the user settings.

rm ~/.jriver/Media\ Center\ 34/Settings/User\ Settings.ini
and restart MC.
If it still segfaults remove both the one above and the Machine Settings.
rm ~/.jriver/Media\ Center\ 34/Settings/Machine\ Settings.ini

If MC still won't start you have other issues.

Hmm might be a bug then, I will check
