I would suspect that the large filecache isn't particularly helpful for Myth... it's writing these large-ish files out, but is not necessarily going to re-access the same file again in the near future. In fact, I find a bit of a delay (as data is pulled off disk) if the box is doing more than one thing at once. For example, watching one thing while recording another, or watching a recording while another is being flagged for commercials. In these cases, pressing I introduces a slight delay, presumably as the images are pulled off disk again and/or the database is queried. Certainly not bad enough to complain about, but sometimes I wonder if Myth might be able to benefit from using Direct IO (if Linux has this capability). Filesystem cache might benefit LiveTV, though. But, this is all just speculation. I am, unfortunately, not familiar enough with the internals to say for sure. aaron
