[mythtv-users] poor quality tv from pcHDTV (dvb)

[Mark Fischer]

I'm having very poor quality tv from my pcHDTV 3000 card.
About my system:
AMD 3800+ X2 64 bit
2x1GB PC3200 dual channel memory
250gb SATA Hard Drive WD Caviar
pcHDTV 3000
Nvidia GeForce 6600 on PCI Express 16X
MSI K8N Neo4 Platinum mainboard

I've been testing directly with mplayer like:  mplayer -nosound dvb://
I've tried all the -vo options. Of those that "work", the image is
highly pixelated and it seems to be rendering very slowly.  I believe
this has to the with the capture card because I've played back an HD
trailer of Pirates of the caribean with mplayer and it plays back
fine.

My capture card is fed with a digital cable signal. I've read the wiki
on these topics:

azap output has sporatic loss of locks:

and mplayer will sometimes reports errors like these:
a52: CRC check failed!
a52: CRC check failed!
a52: error at resampling
