This might indeed be the problem. Setting the "option strip-height" or using a<br>
|
|
higher resolution, everything works fine.<br>
|
|
At the moment I solved the problem by setting strip-height 3, which makes<br>
|
|
lineart mode work, but slows down the other modes and the preview.<br>
|
|
<p>
|
|
I've already tried to set a longer timeout in the low level SCSI driver<br>
|
|
(aha1542), but I've not yet found the setting. There are a lot of "wait times"<br>
|
|
set, but no timeout. Does anybody happen to know what to change?<br>
|
|
I don't want to try out the settings one after the other, as after each try that<br>
|
|
failed, I have to reboot the computer...<br>
|
|
<p>
|
|
Ciao, Michael<br>
