"Finicky" DVD Players


I own a Sony DVP-S7700 and a Denon 1500. Both of these DVD players are VERY particular as to what and WHEN they will play certain DVD's. I have 2 computors with DVD capability , both of which will play these DVD's anytime. I have noticed that many times (when I buy a used DVD from say:-Blockbuster- that the DVD player will not recognize that there is a disk inserted or says that it cannot read the disk. I can sometimes get this "refusal" and later on it will play with no ploblem. What's up?. Do I have to buy an EXTREMELY cheap unit to solve this problem?

Thanks for your help

Steve:

The SONY DVP S7700 is from circa 2000 (my SONY DVP S560D is from the same production year). Other than redbook CD's (no CDR-R or CDR-RW's) and production DVD's, the SONY's will not play anything else. You can go on Google and search on "SONY C13:00" and spend the next few hours reading away. I know that this could imply that Blockbuster's DVD's could be DVD+; DVD-; etc. and I don't know enough to say either way.

DVD players have improved tremendously since 2000. I just upgraded to a SONY DVD recorder (the SONY GX300 for $350) which recognizes most variations on the DVD theme. If it is just a DVD player that you want, take a look at Panasonic's F87/97 (single player/changer) for $90-$115. Super build and super performer and it recognizes at least a dozen different formats/variations.

I will post an old question here, my Samsung HD841 makes a digital kind of gurggled sound, but the picture plays seamlessly, any ideas of why? thanks Chad
My 7700 plays CD-R and DVDR.
I own 700 dvds and they all plays fine.
