Can you post your file sizes for a 1 hour show? Mine are 2.2GB each<br>> at 480x480, all other defaults on my PVR-500.<br><br>I record everything at 720x480 on a PVR-350, and I'm at about 2.2 gigs<br>an hour as well.<br><br>I actually just lost my configuration and had to switch from the<br>default 480x480 back to the 720x480 I normally use.<br><br>Here's an episode of House that I recorded with the default settings<br>(480x480). Filesize is 2332995584 (2.2G). Here are some stats gleaned<br>from mplayer:<br><br>VIDEO: MPEG2 480x480 (aspect 2) 29.970 fps 6000.0 kbps (750.0 kbyte/s)<br>Opening audio decoder: [mp3lib] MPEG layer-2, layer-3<br>AUDIO: 48000 Hz, 2 ch, s16le, 384.0 kbit/25.00% (ratio: 48000->192000)<br>Selected audio codec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3)<br>Movie-Aspect is 1.33:1 - prescaling to correct movie aspect.<br>VO: [xv] 480x480 => 640x480 Planar YV12<br><br>And
to compare, here's another more recent hour-long show, but at<br>720x480. Filesize is 2332057600 (2.2G).
