OK, just a quick followup question. I am trying to make sensible transcoding rules, and I'm not having much luck. Here are the parameters. my FE/BE is a 1GHz P3, and my card is a PVR-150. Currently my recordings are taking about 2GB per hour. I was hoping to cut the sturage needs in half. I turned the RTJPEG quality down to 50 (from the default 170) and it was small, but the quality was bad. I wasn't sure if the MPEG4 encoding/decoding would be CPU intensive for my old P3.

Thanks. That did the trick. I was trying to use the medium setting, and I guess that I never set it up correctly. I switched to autodetect, and thing are great.<br><span class="sg"><br>Matthew Asplund</span><div><span class="e" id="q_10fb2f6157b44981_2">
