Next weekend will have about 50% more players as it's the Tekken 6 release weekend.
Greg, that rog was a pretty bad player, and be wary of mashing out those DP's offline as people will bait you into it for a free reset into another combo.
You really should learn some combo's and block strings too, and what to do after a connected AA dragon punch (EX fireball, super, Ultra etc), as over 70% of your damage was from mashed DP's!
I don't play Ryu but here are some useful combo's:
Punish whiffed moves: f.HP, c.HP, HP dragon punch
Safe "BnB" jump in: MK, c.LP, c.LP, c.MP, Fireball
You can also hit confirm into a dragon punch or hurricane kick by adapting the above combo.
