# Known Issues

The following issues are known to us. We are trying to resolve them in an upcoming version.

- Certain layers do no longer draw straight lines on OS X Lion. Affected layers are Night Sky and Zodiac Signs as well as a few more in preview, like Static Text. Those would usually draw their boundaries in preview. This is due to a bug in OX X Lion. We have are in communcation with Apple and hope to get it fixed soon.
- Some cameras (including the Logitech QuickCam Pro 9000) behave strangely, sometimes stop delivering images and conflict with the built‐in iSight of some MacBook (Pro) computers. We have yet to find out the cause.
- Muxed media files (e.g. movies with filename suffix .mpg) currently can not be used in BoinxTV. To work around this, convert the movie to a QuickTime movie which uses MPEG–4 or the Apple Intermediate formats (a ‘Pro’ licensed QuickTime Player 7 can do this).
- Creating a filtered source with multiple (active) graphics cards in a Mac Pro does currently not work. Only one graphics card can have monitors attached.

The following issues cannot be resolved by Boinx Software.

- When creating custom layers for BoinxTV using Quartz Composer you can quite easily create compositions that will affect the performance and stability of BoinxTV. Specifically you must not use the Video Input and Audio Input pathes as they heavily interfere with BoinxTV.
- De‐interlacing of video from HDV cameras does not work. This is a limitation of QuickTime and we hope that a future version will provide de‐interlacing. Doing it ourselves would be possible but cost a lot of performance. Please check if your HDV camera has a progressive mode—at least some Canon models are able to do progressive HDV, and these work fine with BoinxTV.
- Media files protected by DRM (e.g. protected audio or video files bought from the iTunes Store) cannot be used inside BoinxTV. There is no (legal) way around this, sorry. Upgrade your iTunes media to iTunes Plus if available.
- In certain occasions text gets truncated on the last line in layers, such as the Static Text 3D. This is an issue of the underlying Apple frameworks that will hopefully be fixed soon. As a workaround add an empty line or a few space characters at the end of the text.
- Launching certain audio software (e.g. Apple's GarageBand) causes strange things to happen in Core Audio. BoinxTV (and other apps) can not handle this well and may drop some audio, or even stop audio output completely. As a workaround, never launch any of those applications whilst recording in BoinxTV.
