Ok, here is the situation, and believe me i have read almost every thread here in hopes that i can figure this out. i think i understand the battle of -r and +r, but my problem lies somewhere between that i think. Ok, here we go... i have a pioneer dvr-225,(got it for free because of an old warrantied dvd player broke down, gotta love best buy's extended warranty) anyway, i was totally excited about getting a "burner" for all my tivo shows. i have spent about the last 3 days emptying my tivo, testing them, but like an ass i just tested them on the pioneer itself, when the recorded dvd would play i would then delete the tivo show...bad bad bad bad bad bad bad bad bad bad bad bad bad!!!! i just tried to play one of those newly burnt shows here on my pc and NO it hated it, my pc would not even recognize that there was an dvd in it. now some of you are laughing at me, some of you are saying well at least it plays in yer dvd thingy, well it plays where it was made, but on further tests it does not play in any of the other 3 players in our house. and the oldest of these players is 2years. when i frist put a dvd into the player it was a blank dvd+r and it said..."can't use" on its wee little screen, of course at this time i had no idea to even look for -r or +r whatever, i just learnt that here a min ago. anyway, i got 3 different spindles of blank dvd's this x-mas so i opened a new bundle which just happened to be -r's. and they worked. so i began recording in glee, things were so awesome, and then you know what happened. i do a lot of work in my office on my computer or at my table, i watch tv on my pc and movies as well, i guess my pc is my media center you could say, LOL i even have windows XP media edition, and a friggin' remote now to, so ya its my media center. i really want to bring my tivo collection in here, but have not a clue how to do that... 1.how come my player plays dvd+r's and can't record on tem? 2.how can my computer not read a dvd-r? 3.is there a player/recorder out there that supports both of these types? 4.is it even a -r +r situation here, or is it deeper like ntsc-vs-pal or whatever? 5.is it better to just burn dvd's from your pc? Thanks in Advance for any advice you can send my way, THNAK YOU THANK YOU THANK YOU !!!!!!!!!!!!!!!!!!
