I'm afraid Compressor is not very good at doing that kind of a batch transcode. Use an alternative app like MPEG Streamclip, which is much more efficient than Compressor in processing batches and does faster encodes unless you have a serious cluster set up.

Yes, for most basic conversion tasks, Streamclip is about an order of magnitude faster in transcoding, and two or three (sometimes more) orders of magnitude faster using the interface.
The lag you describe in Compressor happens when using any type of source material not natively supported (i. e. almost anything that is not QuickTime, DV or MPEG-4.)
When requesting any kind of information about the clip, all other formats are first piped through the appropriate preprocessor, e. g. Perian or Flip4Mac. Apparently Compressor does not cache any of these pieces of information, so for every access, the entire preprocessing is done again, which can be an incredible nuisance.
If possible, use Streamclip, which handles "alien" formats much more efficiently, to convert the material to QuickTime, before putting it through Compressor. My advice is to use Compressor only if if you really need it for a special job, such as high-quality framerate conversion, at which it is good, albeit extremely slow.
If you are going to apply the exact same settings to a bunch of files, use a Droplet. There you usually have to wait only three times for the preprocessing to complete: it is normally faster than going through the full Compressor interface hassle.

Thanks so much, that really clears things up. I'll try some other options for transcoding my large batches!
