Thanks for the reply, yes im sending it from Final Cut Pro X to Compressor via the Share menu This used to work but havent used it for the last six month and theres been some patches so not sure if that has affected it or something similar.
I also tried reinstalling and cleaning out library and preference but it did not resolve the issue either.And also repaired disk permissions.
Export from Final Cut Pro X using quick time works fine though so seems the issue is specific to compressor.
Probably should add that my OS is the Server OS but i am not haveing any clusters and there are no other computers connected all processing is local.
I'm not sure. Seems like a lot of the reports of Compressor problems involve the interoperability of FCPX and C. So each might perform properly when used independently but act up when they have to cooperate.
If you take a QT file and give it to Compressor will it complete whatever job you give it?
In addition to the steps you're previously taken I'd reset background processing and repair permissions. Also see if you can isolate any plug-ins or third party apps that are new to your system over that 6 month period.
I have now reinstalled reinstalled FCPX and Compressor again, completely uninstalled Motion.
I tried to give a MOV file to Compressor but result is same. I did then try to just send a clip of just few seconds from FCPX to Compressor and that actually worked, so after this i added a 20 min clip and send again to compressor and the 48 bytes issue appears again , however the computer seem to be still processing, just not saving any data, checked all drives not much activity except that the swap file keeps growing. I have 8 GB so memory should not be an issue.

Really strange,,, Im not sure what else can be done..
The only app i have installed recently is Motion and i have already uninstalled that.I dont have any plugins for FCPX.
Not sure exacly what you meant by background processing in this case but i have deleted all the Qmaster related files.During the reinstallation so there is no exisiting queue.
Although I doubt it would accomplish anything more than you've already done, the reset I had in mind is found in the Compressor menu tool bar under Compressor.
I've re-visited the published Apple trouble shooting document and the only thing I see that we haven't checked is whether the computer's name is entered in Sharing (in the Advanced tab). Is it?
I hope you managed to sort out your problem - I gave up for a long time but I think I found a solution for a similar if not the same issue: https://discussions.apple.com/message/20479332#20479332
basically, I had old versions of compressor still running. By getting rid of them (using terminal because they are installed in /usr/sbin) I got things back up to date.
