Thanks for the info.  I have more questions inline.

I like what you're saying.  A 4X reduction in space used would certainly be welcome.  However, that brings up another question.  Can I produce a h.264/mkv based disc that will be readable on a standard DVD video player attached to the tv?  Or, will I have to play this disc on the computer.  I really need something that just works in an ordinary stand alone device.

Is Video Redo for killing commercials?

What does that do?

Assuming this is for transcoding.

Tell me more about this.

I know what you're saying, but I think, based on the forum posts I've read, I want to go with top tier name brands in each genera of discs, depending on what genera I use.  However, I may relent and not use archival discs.

conventional - TY / JVC
archive -  MAM-A

Can you elaborate on par2.  Do you scan, scrub your discs every 5 years or so to make sure they're still good and determine if they need to be reburned?

Interesting idea.  The portfolios I saw at Frys weren't too impressive though.

The procedure for recording from analog from my DVR will be the same as with the VCR, although it would produce much higher quality.  As far as I know, there is no way to record the HDMI output.  Buying from Hollywood (for example Star Trek) is about $ 3 / show.  That doesn't sound like much until you consider how many shows there are.  I'd like to get by cheaper and still legal.

I made a test recording from my cable box dvr using the analog out and the digitizer I just returned.  There is a .3 sec sound sync variance in the mpeg file between the audio and video.  I can compensate by playing through VLC and tinkering with it but I'd rather fix it then save it.

Sincerely,

Ron
