I currently use a Pinnacle PCTV 800E (normally made for Windows PC's) with EyeTV 3.0 on my iMac. Lately it seems that I get pixelization, stuttering, sound glitches in HD recordings. I've been thinking that I may need to upgrade to a *real* tv tuning adapter made for Mac. I just want to make sure I get something better then my current setup. I record shows and watch live tv, but I don't have cable or satellite tv. Everything I use is HDTV over the air. I've been using the standard stick antenna that came with my adapter, but haven't tried powered rabbit ears. My specs: iMac Core2Duo 2.8GHZ, 4GB Ram, 500GB Hard Disk, Geforce 8800GS 512MB, Mac OS 10.5 Leopard. I've been looking at Elgato EyeTV Hybrid, but in general looks it seems to be almost identical to my current PC tuner I'm using. I want to make sure it isn't. While correcting the video issues is my primary concern, I hope I can find something that is better while I'm spending this much. Any recommendations? I wish I could find something that would record and then auto convert to AVI format, or do it on the fly. I recorded the premier of My Own Worst Enemy and it came in at 7.22GB. The Saturday Night Live Political Special came in at 12GB. Maybe thats normal, but it seems large, even for HDTV.
