Having an old receiver that is still quite dandy aside for the need to do a few workarounds here and there (although it's s-video up-conversion capability seems to have died (so my old s-vhs vcr is stuck with composite
)), you end up trying a lot of different things.
If it didn't have multi-channel PCM (lossless) audio, might be a different story though.
Next thing I'll probably try is seeing if the newer directv hd-dvr I got a couple years ago will behave itself better than the its predecessor, which used to freeze from time to time when doing certain things (mostly fast forward and rewind as I recall) (that and it used to have audio dropouts regardless of how it was hooked up). The workaround for the freezes was to use HDMI for video and coax for audio. Now that 3-D is no longer a directv supported format, no need to bypass the receiver (which does not support 3-D) if the two are more compatible. Which would also free up an HDMI input on my tv. (Thankfully the audio dropouts went away with the new hd-dvr.)
But I ramble... think I'll go try that directv thing out now.
