They where telling me that the NTSC standard is 720x480, although cable broadcasts don't use that high, it's much closer to 480x320. I originally had my resolution for capturing set to the max, but I'll try scaling it down to the true broadcast size, that should save some space.
Since I'm using a very weak box to run the Myth backend on, I'd rather have the size determined while the card is encoding with the hardware MPEG2 encoder.

Now, I just downloaded [bittorrent] an episode of something I missed.
The AVI's ~364 Mb for the, I guess, ~43 mins., but is, whem played
through MythVideo, of comparable quality to the stuff I record at 6x the

Those AVIs you downloaded probably aren't using MPEG-2, but instead use some
variant or another of MPEG-4. That's why they can deliver the same quality in
less space. Comparing MPEG-4 to MPEG-2 is like comparing Ogg Vorbis to MP3.
You could transcode from MPEG-2 to MPEG-4 (MythTV will even do this for you),
but the transcoded recordings won't be playable through your PVR-350. (That
assumes you're using its MPEG-2 decoder; I stopped using mine when I upgraded
to an LCD TV and switched from S-video to DVI.)

I noticed the same thing with downloaded files vs. files captured from my pvr 150, but even when i use mythtranscode to convert them to mpeg-4, i can get downloaded AVI files that look much better and are smaller. Should i use one of the external transcoding programs instead of mythtranscode?
