Which recording profile are you using with the HD-PVR?   "High
Quality", "Low Quality", "Default", "LiveTV", etc?

For that recording profile, what bitrates have you defined for the
different resolutions?  If you are using a "high" bitrate for the
"low" resolution (<720p), then that would result in large files for
standard-def captures.
