HVR-1600 SD quality on LCD
|
|
I am using Mythdora 10.22. I recently upgraded from a 42" SD tv to a 46"
LCD. I use an Explorer 4250 from Cablevision connected to the HVR-1600.
Essentially SD is pretty fuzzy with this setup. DVD playback is clear.
I verified my recording and live tv profiles are set to 720x480. I tried
upping bitrates to 6000 and 7000, but this did not seem to help.
