I recently purchased a Seagate PVR expander from a Shaw retail outlet to connect to my gateway system and I've had nothing but problems. I've formatted the drive several times, but it's constantly causing the playback from recorded programs to freeze and be full of glitches. I now have frequent connection issues with the gateway.... the picture will be lost, screen goes black, and I receive a message to check the connection to the gateway. If I disconnect the PVR expander, the gateway works normally. Recorded shows on the gateway hard drive play back without an issue. Any help?! I'm ready to take the PVR expander back to Shaw.
