I tested that once or twice with my TiVo S3, which can record from cable and OTA. Files for the OTA recordings were slightly larger, but the difference was negligible--100 Kbps or so, generally less than 2%; if they were transrating, the cable companies would go for a reduction in the 20%-30% range. It's been a couple of years since the last time I did that but I doubt that anything's much changed.
