Bell Expressvu is going to enable it's USB 2.0 ports on it's 9242 dual tuner PVR [$599] and the new 6141 [$299] single tuner, making it a PVR, so that we can connect a hard drive up to maybe 750 GB for recording. This should happen this year. Both receivers are for the some day switch to Mpeg 4. I'm pleased with my 9242 and maybe Bell is getting it's mojo back.
