Well, no. It's very stable for the common use cases: capturing and compressing analog video and passing along digital TV from the ATSC/QAM tuner and demodulator. Raw/uncompressed YUV video is a mode almost no one uses with the card. When have you used the YUV mode with your PVR500? I would think you likely never have. Raw YUV capture with the HVR-1600 probably won't matter to you at all - so it doesn't matter if it doesn't work perfectly right now, or ever. ;) > > However, you don't need an MPEG encoder for digital TV.

The ATSC broadcast as sent over the air by the broadcaster is a digital MPEG-2 TS - it's already compressed. No hardware compression is needed on your PC for ATSC or clear QAM, and the HVR-1600 or any USB DTV capture device doesn't need to compress it. You just need a device to tune and pass the MPEG TS stream along to your favorite software decoder: mplayer, MythTV, etc. Regards, Andy _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
