I've used Reon in my 885, so I can offer some comment regarding its use with cable. The Reon chip is a pretty nice video processor, but it's not going to make SD channels look like HD. You'd be hard pressed to find a video processor that would do that. What it can do is make those SD channels look less like an over-compressed and badly-deinterlaced than the cable box will. The cable boxes I've used have dreadful scaling/deinterlacing performance, so if you can set the box to output a basically unprocessed video signal the Reon can do a consistently better job.
