I am subscribed to 2 providers, Rogers and Bell, using SD STBs. Is there a recording device (PVR, DVR, TIVO, etc) that will enable me to efficiently record from both? I would consider upgrading to HD if necessary, but would prefer to stay SD. I am using a VCR to accomplish this now (Rogers inputing into ch 3, Bell into AUX) and this works fine, except for the poor quality and functionality. P.S. Not sure where this post belongs, admin move it if you want. TIA.
