Hmm... I suppose it depends on what you mean by quality.
I record using a PVR-250 with the following settings, and I have no
problem getting 2 hours on a DVD. Granted, we're not talking
DVD-quality video, but I don't think I'm really losing much quality
compared to the original analog cable TV source.
For reference, here are my settings:
Video
Codec: MPEG-2 Hardware Encoder
Streamtype: DVD
Aspect ratio: 4:3
Bitrate: 3000
Max bitrate: 5000
Audio
Codec: MPEG-2 Hardware Encoder
Sampling rate: 32000
Type: Layer II
Bitrate: 320 kbps
Volume: 90%
I use the MPEG2->MPEG2 export option of nuvexport to cut commercials,
so no transcoding takes place.
HTH,
Lane
