problem when LiveTv file changes (only when captions enabled)

[nsti2tion]

Love the program, Sub! thanks so much 4 it.

I'm using v99.12 (pvrx2 seemed too slow on my pc, and this prob happens on it too, i believe). I'm having a problem when the LiveTv file changes (on the hour or half hour, depending). If i have captioning enabled, I can watch live tv and see the caps with no problem. When the LiveTV file changes on the hour/half hour, the video freezes (extended desktop). GBPVR does NOT lockup, just the video - simple right click of mouse returns to GBPVR menu. The program is still recording - confirmed it by watching the file with wmp. Have tried both vmr7 and 9. If i don't have the config set for captions, all is well. (i just prefer to watch tv with cc). This prob occurs whether I have GBPVR set to pc monitor or extended desktop.

some specs:
pvr350 (software mode only as tv-out locks sys on occasion)
soyo sy-p4vtp (celeron 2.4 GHz)
756M ram (soon to be 1.5G)
winxp pro
using tv out of radeon 9600 (on extended desktop) to CRT tv
all drivers up to date

Sorry if this has been asked before, I've been searching the forums for a couple of days and don't see this prob listed.

I'm unsure if this is a vid card problem or not and any help is greatly appreciated.

Switched to v1.0.16 (pvrx2) and get same results. I've been fiddlin with settings on both the Radeon 9600 and Gbpvr but cant figure this out.

Some info on attached logs:
Timeline is from 9pm to just after 10pm. Using Livetv (Livepreview NOT enabled). Watched two 30 minute shows.

Again- it seems that at the 9:30 show change, the video/sound/caption output freezes (nothing locking up though- can right mouse click out to main menu of Gbpvr). Gbpvr keeps recording the 2nd show (with new filename). This only happens with "show closed captions" enabled. Able to get captions natively thru pvr350 after applying some registry tweaks, therfore not using mpg2srt or anything like that.

I also noticed that if i wait a few minutes after the freeze, i can press rewind on the remote a few times and can see the captions/hear the audio from after the freeze. but the video remains frozen.

Anyone got any ideas or heard of this problem?
