EFF Reviews HDTV PVR Solution for Mac 147

Posted by timothy from the moving-about-pictures dept.
enrico_suave points out this "PVRBlog post about EFF's Review of Elgato's EyeTV 500, an HDTV solution for the Mac. Well, a very speedy dual-processor G5 Mac, apparently. The Electronic Frontier Foundation has been doing a lot of important work defending our online and digital rights including opposing the dreaded FCC mandated broadcast flag (cue boos and hisses) Elgato and Plextor also have a Standard Definition homebrew PVR solution with an EyeTV and ConvertX PVR bundle (Wired review)."

      However, suppose that some major media properties persuade Apple to rewrite their firewire drivers, necessitating a a similar driver update from ElGato. The question then becomes: Is ElGato legally required to cripple its software in the course of this update? Could one reinstate compatibility with the old, pre broadcast flag driver by rewriting portions of the Darwin source?

    OK, interesting gadget. I just have a few questions.

    Why do you need such a great CPU? The article says it's because the hidef MPEG2 content is decoded in software. Huh? I though graphics cards started doing MPEG2 assist and later complete MPEG2 decoding years ago? It that feature just not in the drivers, or was it dropped due to cost and faster CPUs? Guess you should budget in some more for an MPEG2 decoder card, but they are not easy to find anymore (at least not as easy as they were), they tend to require passthrough (I've never seen pass-through DVI, and would it handle dual link for 30" screens?), etc. Seems like a big problem.

    Only an antenna? If this thing can record HD and SD content (as long as it's digital), why not give it an HDMI connector so I could record off equiptment that has HDMI out? Or give it a DVI in for recording off that? Just an antenna seems.... measly.

    Interesting though. The CPU problem is not as bad as it sounds considering how many people would currently want to use their computer to timeshift full glory HD content. If you have the TV and such for that and you can afford this box, you can probably afford a computer to play the file (or at least an MEPG2 decoder card).

    A dual G5 requirement for smooth HDTV playback is a big problem. You should be able to easily do this with a midrange G4 system.

    The problem is that Apple has not opened the API for the MPEG2 acceleration available in most of the video chips in Macs. ( The equivalent of DxVA in Windows, or XvMC in XFree86 ). In the x86 world, this takes the CPU requirement down from ~ 2.4GHz P4 to ~ 800MHz P3.

          I know they claim that. What I was reporting is that it is a lie. I had a 700 MHz Athlon which was originally claimed to be sufficient for the Fusion I card (using DxVA) and it was not. I upgraded to a 1500 Athlon and finally the 2400+ which is sufficient for software decoding with DvXA assist. Without DxVA you get a more stable picture but it has to throw out every other scan line. I actually prefer that picture generally because it doesn't have the artifacts that you get with DxVA.

          If someone has an older box with a sub 1 GHz processor he will need to get a MyHD card to get good results. I wouldn't recommend Fusion cards to anyone with less than a 2 GHz processor. I am using the computer monitor. Maybe the picture from the DVI port gives better results with less CPU.

          It has been reported elsewhere in the comments that dual 1 GHz G4 Mac will produce good results with EyeTV 500. If that is the case then the results are not so starkly different. I'm sure the software is less finicky because I have and use EyeTV (I just use it with the EyeTV USB but it is the same software). It doesn't restart the Mac just because I commit the mistake of running VLC or some other video program. In fact on the Mac I have the option of having multiple programs running at the same time without causing a crash.
