OT Re: DVD Recording/playback

I did quite a bit of searching for reliable info on media quality/reliability and retention, after reading about poor quality archiving/backup media here in RCM (so there are probably others that have or will have these questions eventually).

Nearly all of the info I found stated a few common practices:

- use a disk identifier feature of the burner software (or separate software) to see the actual maker and characteristics of the media, and check lists that are available to see if the disks are worthwhile for archiving valuable data.

- always record at about half of the speed rating of the media, if the disks are rated 12X, then select 6X in the burning software (think sears horsepower numbers).

- many sources indicated that Taiyo Yuden is the best brand of disk, made in Japan, and that the best place to buy them in the U.S.A. (to avoid counterfeit disks) is SuperMediaStore.com

A couple of sites for info (or search DVD quality retention or similar terms)

As far as the video signal dropout situations, it's probably best to use an electronic signal enhancer device between the source and recorder. One of my cheap consumer DVD recorder/player decks will display an error, something like "low video signal level" when copying from video tape and even from another DVD source.
Signal enhancers are intended to keep the input signal above a specific minimum level.

Tapping the vast knowledge database...

OK, I haven't thought this through completely before posting, but...
I have 2 DVD recorders, one Toshiba DVD-R, one Sanyo DVD+R/DVD+RW. Both work well.
Movies recorded on either won't play properly on DVD 'players' like my Toshiba 9"TV/DVD or my new Audiovox 15" LCD TV/DVD. Recorded Discs from both recorders will start OK, but 5-15 minutes into the first title, start displaying digital artifacts, then eventually stall. Neither will play a second title.
I know various manufacturers state that their units may not play discs recorded on other units. What's up with that? Just what is 'Versatile' about DVD that makes it so un-versitile?
Before I start really raving on the absurdity of this bull***, and just exactly what's wrong with the consuming public that this is tolerated, let me digress.
/rant
Are there variables like disc brand, Xspeed rating, recorder settings(SP/LP, etc),that have been known to influence this fault in a positive direction? I don't really want to embark on a lengthy experiment by buying all the different disc choices and testing, only to come up unsuccessful.
I bought both DVD players to play my recorded DVDs on my boat. As of now, this plan is defunct.
More information later...
Any input?
JR
